Editing Turkish Articles: Spelling and Punctuation Checks

If you publish or commission Turkish articles and do not read Turkish natively, article editing is the step most likely to be skipped, and it is the step where small errors pile up. A Turkish article can look fine at a glance and still carry a wrong capital letter on a month name, a misplaced apostrophe before a suffix, a missing "ğ" or three different spellings of the same product term. Editing Turkish articles means checking spelling, punctuation and consistency in a systematic way, not just running a spell checker and hoping for the best.

This guide is written for editors, agency managers and content buyers who order or review Turkish-language content, whether from freelancers, agencies or a marketplace. It explains what each editing pass catches, which rules of the Turkish Language Association (Türk Dil Kurumu, TDK) decide the common edge cases, how to keep a bilingual style sheet and how to review a draft when you cannot read every word yourself. I read the TDK pages cited below directly and give their dates in the text; where I could not read a page, I do not claim a rule. All sample sentences are invented for teaching purposes and do not come from any real client or publication.

Why Editing Turkish Is Different

Suffixes carry grammar, so errors hide inside words

Turkish is an agglutinative language: case, possession, plurality and tense are added as suffixes to the end of a word. In English, a spelling mistake usually changes one visible word. In Turkish, the same mistake can sit in a suffix and turn a correct sentence into a wrong one without producing a non-word, which is exactly what a spell checker looks for. A suffix that does not match the preceding vowel or consonant may pass tools that only compare each word against a dictionary.

Six special letters decide whether a text looks native

The characters ç, ğ, ı, ö, ş and ü are separate letters of the Turkish alphabet, not decorated variants of c, g, i, o, s and u. Texts that were retyped on a keyboard without Turkish layout, or that passed through a system that strips accents, lose them silently. Because the stripped form is sometimes still a real word (for example "sac" and "saç" are different words), the loss is not always caught by software. Your reviewer, or your Turkish-reading colleague, has to look for it.

The dotted and dotless i

Turkish has two letters i: the dotted "i" with the capital "İ", and the dotless "ı" with the capital "I". Software that does not apply Turkish locale rules turns "iş" into "IŞ" when it uppercases a heading, while the correct capital form is "İŞ". If your content management system or style template uppercases titles automatically, check the output by eye. The same character issues affect keyword work, which I covered separately in this guide to Turkish keyword research.

Roles: Who Edits What When You Order Content

In small teams one person plays writer, editor and proofreader, yet the three jobs are different. The writer builds the argument and produces the text. The editor judges the text as a whole against the brief: structure, accuracy, tone, consistency and sources. The proofreader works line by line on spelling and punctuation. When one person does everything, errors survive, because a writer reads what they meant to write, not what is on the page.

If you buy articles, decide in the brief who owns each role. Many problems that look like writer errors are actually brief problems: nobody said which spelling reference to use, nobody shared a term list and nobody said whether the writer or the buyer would proof the final file. The practical split between roles is discussed in more depth in our piece on the writer and editor workflow.

Editing is also not strategy. Topic choice, keyword targeting and audience are decided before drafting. An editor checks that the decided frame is applied; asking for a rewrite is a revision request, and it should be named as one so that a spelling fix and a new article are not confused in the same message.

Which Reference Should Decide?

For Turkish spelling and punctuation, the standard reference is the Spelling Guide (Yazım Kılavuzu) published by the Turkish Language Association (TDK), together with the spelling rules pages on its website. When you brief a Turkish writer, name this reference and say that the current edition applies. That way the writer and the reviewer consult the same source when they disagree.

Two cautions. First, a reference tells you the rule where a rule exists; in many places it leaves room, and you have to decide a house style. Second, rule pages can be updated, so note the date on which you checked. I read these TDK pages on 28 October 2026, and I list their dates below with each rule.

The Six Editing Passes

Trying to catch meaning, commas and terminology in one read is inefficient, because attention narrows to one kind of error. A more reliable method is to read the draft several times with a different question each time. The order below is a heuristic and can be adapted, but it is sensible to settle structure and accuracy before spelling, since there is no point proofing a paragraph that will be deleted.

The sixth pass is the one buyers forget. It is part of publication quality, and our content quality checklist before you publish covers it in a wider scope; this article concentrates on the Turkish spelling and consistency side.

Spelling: What Tools Catch and What They Miss

Spell checkers in word processors and browsers flag words that are not in their dictionary. That is useful and should always be switched on, set to Turkish. But a checker works by word, not by sentence, so it frequently misses errors where the written form is a real word in the wrong place. It may flag "yanlız" for "yalnız" (alone, only), yet be unreliable on whether a "de" is a conjunction written separately or a locative suffix written attached to the word. Treat tool output as suggestions.

Tools also produce false alarms for brand names, product names and domain names. Add them to a custom dictionary, and do it with care: adding a misspelled word to the dictionary hides the error permanently.

The following problems are likely to pass a checker and should be searched for by a human reader:

• The conjunction "de/da": according to the relevant TDK page, the conjunction "de/da" is written separately from the preceding word, never as "ta/te", and is not separated by an apostrophe ("Ayşe de geldi" is correct, "Ayşe'de geldi" is wrong). The page is dated 13 February 2019. It does not separately discuss how to tell the conjunction from the attached locative suffix, so confirm doubtful cases in the current Spelling Guide.
• The conjunction "ki": according to the TDK "ki" page, the conjunction is written separately ("bilmem ki", "demek ki"), while fixed words such as "belki", "çünkü" and "sanki" are written as one word. The page is dated 12 February 2019.
• The question particle "mi": according to the relevant TDK page, the particle is written separately and follows the vowel harmony of the preceding word ("Kaldı mı?"), while suffixes after it are attached to it ("Verecek misin?"). Glued forms such as "gelecekmi" are therefore wrong and can slip through some tools. The page is dated 20 January 2019.
• Word choice errors: correctly spelled words that are wrong in context are found only by reading.
• Lost characters: "başladı" typed as "basladı" is a non-word and will be flagged, but a loss that produces another real word may not be.
• Copy-paste residue: double spaces, hyphens at line breaks and quote marks from different sources.

Finding a misspelled word and finding a wrong word are different skills. For the second one, reading the text aloud, or reading paragraphs from last to first, helps because it breaks the habit of reading for meaning.

Capitalization According to TDK

The TDK page "Büyük Harflerin Kullanıldığı Yerler" (where capital letters are used) lists the rules item by item. Its publication date appears as 8 February 2019, and the page metadata shows an update on 8 January 2026. Below I paraphrase the points that most often create decisions in articles. For the exact wording and exceptions, read the page itself.

Sentence starts, proper names and institutions

A sentence begins with a capital letter, and so does a sentence inside quotation marks or parentheses. Personal names, surnames, nicknames, language and dialect names, state names, and names of continents, regions, provinces, districts and neighbourhoods are capitalized. Every word of the name of an institution, organization or board is capitalized, and so is every word in the names of laws, regulations and by-laws. The page also says that words such as institution, law or office are capitalized when they refer to a specific institution or text.

For English-speaking editors, the practical point is that Turkish capitalizes language names (Türkçe, İngilizce) and the names of specific institutions, but not generic nouns. A sentence about "the ministry" in general stays lower case; a sentence naming a particular ministry takes capitals. A text that mixes the two uses looks inconsistent to a Turkish reader.

Month and day names

According to the page, month and day names are capitalized when they refer to a specific date and written in lower case when they do not. A date such as "17 Aralık" (17 December) takes a capital, whereas a general remark that "aralık ayı" (the month of December) is usually busy does not. This is a frequent error in newsletters and calendar content written by people whose own language always capitalizes months.

Titles and subheadings

This item matters for blog editing. The page says that in books and articles all words of the main title are capitalized, while in subheadings only the first letter is capitalized. For names of books, magazines, newspapers and works of art, every word is capitalized, except words such as "ve" (and), "ile" (with) or "de" and the question particle, which stay in lower case. Many Turkish blogs capitalize every word of every subheading as well. That can be a deliberate house style, but it is different from what the TDK page describes for subheadings, so choose consciously and apply it across all articles.

Punctuation Rules That Trip Up Foreign Editors

The TDK page "Noktalama İşaretleri" (punctuation marks) covers the period, comma, semicolon, colon, ellipsis, quotation marks, brackets, apostrophe and others. The page shows 26 January 2019 as its date, and its source information lists an update on 12 September 2023. Four marks cause most of the questions.

The comma

According to the page, the comma goes between items of equal function listed one after another, between sequential clauses, after a subject that has drifted far from its predicate, around parenthetical words and clauses, and after forms of address. It also separates decimals, for example 0,45. The page includes a warning relevant to English writers: no comma is used before or after conjunctions such as "ve" (and), "veya" (or) and "yahut" (or). In other words, the English habit of a comma before "and" in a list, the so-called Oxford comma, does not carry over into Turkish.

In practice: in "Başlık, açıklama ve görsel hazır" (the title, description and image are ready), the first items are separated by a comma and the last two are joined by "ve" with no comma. For parenthetical words, as in "Metin, brife göre, bir gün içinde teslim edildi" (the text was delivered within a day, according to the brief), the interrupting phrase sits between two commas.

The apostrophe

According to the TDK page on the apostrophe, possessive, case and predicate suffixes on proper nouns are separated by an apostrophe. The same applies to abbreviations and numbers; examples on the page include TBMM'nin and 1985'te. It is also used with specific dates, as in "17 Aralık'a kadar". The page lists exceptions too: suffixes on the names of institutions, organizations and workplaces are not separated by an apostrophe (it gives "Türk Dil Kurumundan" as an example), and derivational suffixes and the plural suffix on proper nouns are not separated either, as in "Türklük", "Ahmetler" and "Konyalı".

The grey zone for commercial content is the brand or domain name. Whether a company name counts as an institution name or an ordinary proper noun is sometimes open to interpretation. Do not mix both forms of suffixing for the same brand; make one decision and record it in the style sheet. Where the reference leaves room, consistency matters as much as correctness.

Quotation marks

The page says quotation marks enclose words quoted from another person or text, words that are specially emphasized, titles of works and section titles. Punctuation at the end of a quoted sentence stays inside the quotation marks, and a quote within a quote uses single quotation marks. If your article quotes someone, quote only from a source you have read yourself and mark it. Our guide to citing sources in articles goes deeper into attribution practice.

Colon, semicolon and ellipsis

The colon is placed at the end of a sentence that introduces an example or explanation. The semicolon separates categories that already contain commas and sequential clauses with commas inside them. The ellipsis marks an incomplete statement or omitted words in a quotation, and the page adds that two or more periods are not used in its place. Blog drafts usually overuse these marks; a plainer text that keeps the semicolon for lists that truly need it is easier to read.

Numbers, Abbreviations and Dates

Numbers

The TDK page "Sayıların Yazılışı" (writing numbers) is dated 23 January 2019, with page metadata showing a modification on 16 July 2021. It says numbers can be written in words or digits, and that digits are used for clock times, money amounts, measurements and statistics. Numbers made of several words are written separately. Numbers with four or more digits are grouped in threes from the right, separated by periods, and decimals use a comma. The percent sign is attached to the number, as in %25, and ordinals are written either with a period after the digits or with an apostrophe and suffix, never both: "8'inci" is correct, "8.'inci" is not. The page also says that a sentence should not begin with a digit unless necessary.

For an English-speaking editor the visible trap is the separators. A figure such as 49.750.812 uses periods as thousands separators and 15,2 uses a comma as the decimal mark, the reverse of English practice. Check every number that came from an English source or a spreadsheet.

Where the page allows both words and digits, a threshold is a house decision. Many teams spell out small numbers and use digits for measurements and statistics, but that is a team preference, not a TDK rule, and it should be presented that way.

Abbreviations

According to the TDK page "Kısaltmalar" (abbreviations), capital-letter abbreviations do not take periods, with T.C. and T. as exceptions. Suffixes on lower-case abbreviations follow the pronunciation of the full word, while suffixes on capital-letter abbreviations follow the pronunciation of the last letter, or the spoken form when the abbreviation is read as a word. The page is dated 30 January 2019, with an update in the metadata on 12 September 2023. A practical habit is to spell the abbreviation out on first use and keep one form afterwards.

Dates and currency

I do not give a TDK rule for date format or currency format here, because I did not read a page on them. Decide between "28 Ekim 2026" and "28.10.2026" in your style sheet and do not mix them. When the audience is international, writing the month as a word avoids day-month confusion.

Consistency: A Bilingual Style Sheet

A text can be spelled correctly and still be inconsistent. If one article writes "e-posta", another "mail" and a third "eposta" for email, a reader wonders whether they are the same thing. The remedy is a short style sheet. A style sheet does not invent rules; it records the decisions the team has made. For teams that commission Turkish content from an English-speaking office, the most useful format is a bilingual glossary. The example below is fictional and its entries are house choices, not TDK rules.

When you order many articles, the same sheet has to reach every writer and be applied in the same way across a calendar. For that scale issue, see our note on bulk article orders and consistency. A simple spreadsheet is enough: the term, the accepted form, the rejected forms, the date of the decision and who decided.

Tone entries such as formal "siz" address belong to the brand voice, which is a separate document; our brand voice guide for content writers shows how to write it down. When you use find and replace to enforce a term, search for suffixed forms too ("e-posta", "e-postayı", "e-postalar") and confirm each replacement individually. Blind replacement is a good way to create new errors in a language where the suffix depends on the stem.

Reviewing Turkish When You Do Not Read Turkish

You can still manage quality if you cannot read the language. These steps do not replace a native reader, but they make the work checkable:

1. Ask the writer for a short change log or a note of the style decisions they applied.
2. Run the Turkish spell checker and look at the number and type of flags, not only whether they are resolved.
3. Check numbers and dates yourself, since the separator conventions differ.
4. Search for the brand and product terms in your glossary and count the spelling variants.
5. Check that headings, lists and links work and that the page structure matches the brief.
6. Use a second Turkish-reading reviewer for high-stakes pieces rather than relying on machine translation back into English.

Back-translation through a machine is useful for spotting meaning gaps, but it does not show spelling and punctuation errors, because the tool often silently corrects or ignores them. Treat it as a meaning check only.

Fact Checking and AI-Assisted Drafts

Correct spelling does not mean correct facts

A flawless sentence can state something false. Every factual claim needs an answer to "is there a source, is it current and is it quoted accurately?" Figures, dates, institution names, legal statements and product features come first. Prefer primary or official sources; seeing a statistic repeated on another blog does not prove it. If you cannot reach the source, do not publish the claim. I applied the same rule to this article: rules from TDK pages I could read are included, and no rule is asserted from a page I could not read.

Google's helpful content guidance, which I read in the version dated 5 October 2026, lists among its self-assessment questions whether content has spelling or stylistic issues, whether it appears sloppy or hastily produced, and whether it has easily verified factual errors. These are questions for the author, not a ranking formula, and I make no claim that spelling errors alone cause a ranking penalty.

Drafts produced with AI tools

When a draft comes from an AI tool, editing matters more. Tools produce fluent Turkish but can invent sources, misname an institution or give examples that do not exist. Do the factual pass before you correct commas, because proofing a false sentence wastes time. Our article on AI-written articles and human editing explains where the human editor is indispensable; this guide supplies the Turkish spelling and consistency side of that job.

Worked Example: Editing an Invented Paragraph

The paragraph below is invented for this article and does not come from any client or publication. The errors are deliberate. An English gloss follows for non-readers.

Yeni kampanyamız 3 mart'ta basladı. Kampanya "Yaz Fırsatları" adıyla, Istanbul'da ve Ankara'da, yayınlanacak. Tüm Müşterilerimize mail gönderdik ama herkez bilgi almadı.

Gloss: "Our new campaign started on 3 March. The campaign will run under the name 'Summer Opportunities' in Istanbul and Ankara. We sent an email to all our customers, but not everybody received the information."

A spell checker would very likely flag "basladı" and "herkez", and might flag "Istanbul". The stray comma, the lower-case month name and the capitalized common noun are far more likely to be found by a person. The corrected text reads: "Yeni kampanyamız 3 Mart'ta başladı. Kampanya "Yaz Fırsatları" adıyla İstanbul'da ve Ankara'da yayınlanacak. Tüm müşterilerimize e-posta gönderdik ama herkes bilgi almadı."

Pre-Delivery Checklist for Turkish Articles

1. Do the title, subheadings and opening paragraph deliver what the brief promised?
2. Does every factual claim have a source, and are dates current?
3. Are brand, product, person and institution names spelled in one form?
4. Have de/da, ki, mi and joined or separated words been read by eye?
5. Does capitalization (proper names, months, days, headings) follow the style sheet?
6. Are apostrophes used consistently for proper names, abbreviations and numbers?
7. Are commas, semicolons and ellipses used only where needed?
8. Do numbers, dates, money and measures follow one convention, including separators?
9. Are lost Turkish characters and copy-paste residue cleaned?
10. Do headings follow a sensible hierarchy and do lists and tables render properly?
11. Do links go to the right page and carry meaningful link text?
12. Are quotations verified against their source and credited?

Review this list for every new writer or topic and remove or add items so it becomes a tool for your own team.

Managing Editing as a Buyer

Write the editing scope into the brief

State that the file must be delivered spell-checked and proofread, share your style sheet and name the spelling reference that applies. Giving the writer your existing terms is faster than letting them invent their own. The broader process for briefing writers is covered in our article writing services guide.

Make revision requests concrete

General feedback such as "the text feels careless" slows revisions down. Quote the problem, its location and the expected form: "paragraph 3, 'herkez' should be 'herkes'; replace 'mail' with 'e-posta' throughout." How revision rounds and delivery checks work is described in our article revision process guide.

Check what your provider's terms cover

Whether spelling and punctuation corrections are free, and whether a rewrite counts as a new job, depends on the terms of the provider. I do not claim a general rule here; read the terms before ordering.

Common Editing Mistakes

• Trying to fix everything in one pass: proofing lines while structural problems remain wastes effort.
• Accepting every tool suggestion: a checker can turn a correct form into a wrong one.
• Adding a wrong word to the custom dictionary: the error is hidden for good.
• Applying a style decision in one article only: consistency belongs to the whole publication.
• Leaving unsourced claims after a spelling pass: a correctly spelled falsehood is still false.
• Confusing a TDK rule with a team preference: an editor should know which is which and say so in feedback.

Frequently Asked Questions

What is Turkish article editing?

Turkish article editing is the systematic review of a Turkish text before publication for structure, accuracy, consistency, spelling and punctuation. It does not change the author's idea; it makes sure the text fits the brief, the brand voice and the reader.

Is a spell checker enough for Turkish content?

No. A spell checker finds words that are not in its dictionary, but it often misses context-dependent errors, suffix and conjunction confusion, capitalization and apostrophe decisions, and inconsistency between articles. Read its output as suggestions and add a human pass.

Which reference should I use for Turkish spelling rules?

The current Spelling Guide of the Turkish Language Association (TDK) and the spelling rule pages on its website are the standard reference. Where the guide does not impose a single form, such as whether to write small numbers in words or digits, the team makes a choice and records it in the style sheet.

Why do Turkish numbers look different from English ones?

According to the TDK page on writing numbers, thousands are grouped with periods and decimals are written with a comma, so 49.750.812 and 15,2 follow Turkish convention. Editors who convert figures from English or spreadsheets should check every number for separators.

How can I review Turkish if I do not read it?

Combine a Turkish spell checker, a bilingual glossary search for your key terms, your own check of numbers, dates and links, and a change log from the writer. For high-stakes pieces, ask a Turkish-reading reviewer for a final pass instead of relying on machine back-translation.

Do spelling errors directly hurt SEO?

I do not claim that spelling errors alone cause a ranking penalty. Google's helpful content guidance asks authors to consider whether content has spelling or stylistic issues and appears carefully produced. That is a self-assessment question, not a ranking guarantee.

Conclusion and Next Step

Editing Turkish articles is not finished by one tool or one reading. Structure and accuracy come first, then consistency, spelling and punctuation. The TDK pages on capitalization, punctuation, numbers and abbreviations settle many decisions, and where they leave room, a short bilingual style sheet settles the rest. Telling a rule from a team preference is part of the editor's job.
