El Turco supplies Greek translation and localization services to enterprises, language service providers and AI teams targeting Greece and Cyprus. Every Greek job is translated by a native linguist and checked by a second one under ISO 17100, with ISO 18587 governing machine translation post-editing. Our Istanbul production office manages the projects, and our headquarters are in London.

Greek localization is shaped by its own alphabet and a rich inflection system. Greek has three genders and four cases, marks stress with an accent on most words and drops that accent in all-caps text, so a string that looks right in a spreadsheet can break once it reaches a button or a banner. Our Greek linguists can work in RWS Trados, memoQ, Phrase or XTM. No Greek file leaves us without a pass through What's Wrong?, the QA tool we developed in-house.

Dialects and variants

Greece or Cyprus: which Greek do we translate into?

Standard Modern Greek is the written norm for business, media, software and public administration in Greece and Cyprus. Spoken dialects differ in pronunciation and vocabulary, which matters for speech data, but written business content follows one standard. Spelling follows the monotonic system, which marks stress with a single accent.

  • Standard Modern Greek (Greece)

    Used for most software, e-commerce, marketing, legal and technical projects. Greek is an official EU language, and IATE already holds its EU terminology.

  • Greek for Cyprus

    Written content follows Standard Modern Greek. Cypriot Greek is the everyday spoken variety, and some administrative and legal terms differ from usage in Greece, so we flag Cyprus as a separate locale when the content is regulated or local.

  • Polytonic and historical Greek

    The polytonic system survives in religious, classical and some literary texts. Business content is monotonic, and Ancient Greek is a separate specialist brief.

Script and layout

Writing system and layout notes

Greek uses its own alphabet, written left to right. Most words of more than one syllable carry an accent mark (tonos) on the stressed vowel, and a diaeresis (dialytika) shows that two vowels are pronounced separately. Lowercase sigma has two shapes: σ inside a word and ς at the end of a word.

  • All-caps text: Greek capitals drop the accent (Αθήνα becomes ΑΘΗΝΑ). A dialytika appears where the accent kept two vowels apart (Κάιρο becomes ΚΑΪΡΟ). A plain toUpperCase() keeps the accents, and CSS text-transform applies the Greek rule only for text tagged as el, so we test uppercase labels in the build.
  • Punctuation: the Greek question mark is the semicolon sign (;) and the raised dot (·) works as a semicolon. Code that appends "?" shows an English question mark, while a stray English semicolon reads as a question. Quotation marks are «…».
  • Numbers, prices and dates: comma as decimal separator, period for thousands, the euro sign after the amount (1.250,50 €) and dates as 04/11/2026. Written dates put the month in the genitive case (4 Νοεμβρίου 2026), while a calendar header uses the nominative form (Νοέμβριος).
  • Look-alike letters: Greek capitals such as Α, Β, Ε, Η, Κ, Ο, Ρ, Τ and Χ look identical to Latin letters. A Latin letter inside a Greek word breaks search and spell checking, so our QA scans for mixed-script words.
  • Fonts and expansion: many display and game fonts lack Greek glyphs. Greek text also tends to run longer than English, so buttons and table headers need room.

Localization pitfalls

What makes Greek localization different?

Concrete issues our Greek linguists and engineers check for on every project.

  • Gender and case around placeholders

    Articles and adjectives agree with the gender, number and case of the noun. "Delete {item}" cannot carry the right article if the variable can be any noun, so we rewrite such strings with a fixed noun before the placeholder or request variants.

  • Names in greetings

    Greek addresses people in the vocative case, which changes many masculine names: Γιώργος becomes Γιώργο in "Dear {name}". The word for "dear" also changes with gender, so email templates need a neutral greeting or variants.

  • Formality: εσείς versus εσύ

    Banks, public services and B2B software use the formal plural "εσείς", while games and consumer apps often use informal "εσύ". Verb endings change with the choice, so it is set once per product and recorded in the style guide.

  • Plurals and agreement

    CLDR gives Greek two plural categories, "one" and "other", but the adjective changes with the noun as well: "1 νέο μήνυμα" and "5 νέα μηνύματα" for new messages. ICU messages are tested with real numbers before delivery.

  • Accent-free search and Greeklish

    Users often type Greek search queries without accents or in Latin letters, a style called Greeklish. Store search, filters and SEO slugs need accent folding and transliteration, ideally following the ELOT 743 standard.

  • Regulated and legal language

    Greek wording for EU legislation, product labels and medicines information is standardized. Legal Greek also keeps vocabulary from Katharevousa, the formal register once used in law and administration. Legal text therefore goes to a legal-domain linguist.

Services

Greek services we offer

Every service below is available in Greek. Pricing is per-word, hourly or project-based, quoted after scoping.

AI training data

Greek AI training data

Models trained mostly on English data often get Greek accents, case endings and register wrong. Many also misread Greeklish. El Turco builds Greek datasets for teams correcting that: speech collection across regions, age groups and recording conditions, including Cypriot speakers where needed, transcription, text annotation for intent, sentiment and named entities, RLHF ranking of Greek model responses, moderation data that covers slang and Greeklish and parallel corpora for custom MT or LLM fine-tuning. Every Greek project follows guidelines agreed with the client and tracks inter-annotator agreement per delivery, starting with a free pilot batch.

FAQ

Greek translation FAQ

Which source languages does El Turco translate into Greek?

Greek is translated at El Turco from six source languages: English, German, French, Chinese, Turkish and Arabic. The reverse direction, Greek into English, is offered as well. Companies working between Türkiye and Greece often need Turkish to Greek, while German is a common source for engineering and automotive files. Further source languages are quoted on request, subject to Greek linguist availability.

Do you localize Greek for Cyprus as well as Greece?

Yes. Greek content for Cyprus follows Standard Modern Greek, so one translation usually serves both markets. El Turco flags Cyprus as a separate locale when content is regulated or local, because some administrative and legal terms differ from usage in Greece. Marketing copy may also need adaptation for Cypriot audiences, which we handle as a transcreation brief.

How do you handle Greek case, gender and plurals in software strings?

Greek UI strings go to linguists who review the code context before translating. Placeholders that would need an agreeing article, adjective or vocative ending are rewritten so the variable stands alone. Where that fails, the developer is asked for variants. ICU "one" and "other" messages are tested with real numbers, and uppercase labels are checked for unwanted accents in the build.

How well does machine translation handle Greek?

Machine translation handles some Greek content acceptably but still slips on agreement, register, accents in capitals and terminology. Greek MTPE at El Turco runs under ISO 18587: the engine is tested on samples of your files, the post-editing level is agreed and native Greek linguists post-edit. Marketing, legal and UI text should be translated by people from the start.

Who are the Greek linguists behind El Turco projects?

El Turco assigns Greek work to native Greek linguists with matching subject expertise, and our Istanbul office handles project management. A second native Greek linguist revises each job in line with ISO 17100. Every linguist signs an NDA before receiving files. Work stays in the client CAT tool or ours under our ISO/IEC 27001 certified security controls.

What does a company send to start a Greek localization project?

To start a Greek localization project, a company sends the content type, volume, source language and timeline through the contact form. Enterprises can request a free pilot, and LSPs receive a free test translation of up to 300 words. The glossary, style guide, Greece or Cyprus locale and file formats are agreed next. Pricing is per-word, hourly or project-based, quoted after scoping.
