-daş/-taş
Fellow (-daş)
The suffix -daş/-taş (and its front-vowel variant -deş/-teş) creates nouns that describe a relationship of sharing. It is the Turkish equivalent of English terms like 'fellow', 'co-', or '-mate'.
How It Works
The suffix -daş is a powerful tool for creating words that imply a horizontal relationship or partnership.
1. Morphological Rules:
- Vowel Harmony: It uses -daş for back vowels (a, ı, o, u) and -deş for front vowels (e, i, ö, ü).
- Consonant Assimilation: The 'd' changes to 't' (-taş/-teş) if the noun ends in a voiceless consonant (f, s, t, k, ç, ş, h, p).
2. Usage Categories:
- People: Used for social roles like arkadaş (friend, from 'back-fellow') or vatandaş (citizen, from 'homeland-fellow').
- Technical/Abstract: Used in linguistics and science, such as anlamdaş (synonym, lit. 'meaning-fellow') or doğrudaş (collinear, lit. 'line-fellow').
3. Historical and Irregular Examples:
- Kardeş: The word for sibling is the most famous historical evolution of this suffix, coming from karındaş (one who shares the same womb/belly).
- Harmony Exceptions: Some words are 'fossilized' and do not follow modern vowel harmony. Common examples include meslektaş (colleague), dindaş (coreligionist), and gönüldaş (kindred spirit), which retain the back-vowel suffix despite the root vowels.

- Biz uzun yıllardır meslektaşız.
We have been colleagues for many years.
Word by Word: We long years-for profession-fellow-are.
Here, 'meslektaş' (colleague) is formed from 'meslek' (profession). Note that it is a historical exception to vowel harmony.
- O benim çocukluk arkadaşım.
He/she is my childhood friend.
Word by Word: He/she my childhood back-fellow-my.
'Arkadaş' is one of the most common words using this suffix, literally meaning someone who has your back.
- Yeni projenin birçok paydaşı var.
The new project has many stakeholders.
Word by Word: New project-of many share-fellow-its there-is.
'Paydaş' (stakeholder) comes from 'pay' (share), showing how the suffix is used in modern business contexts.
- Aynı ismi taşıyan kişilere adaş denir.
People who carry the same name are called namesakes.
Word by Word: Same name-acc carrying people-to name-fellow is-called.
'Adaş' (namesake) is a unique case where one 'd' is dropped from 'ad' + 'daş'.
- Vatandaşlar bu karara tepki gösterdi.
Citizens reacted to this decision.
Word by Word: Homeland-fellows this decision-to reaction showed.
'Vatandaş' (citizen) comes from 'vatan' (homeland).
Common Mistakes
Confusing the suffix -daş with the locative case -da.
Yoldaş bekliyorum.Yolda bekliyorum.If you mean 'I am waiting on the road,' use the locative case (-da). 'Yoldaş' means 'comrade' or 'fellow traveler'.
Over-harmonizing fossilized words.
O benim meslekteşim.O benim meslektaşım.While modern Turkish follows vowel harmony, older words like 'meslektaş' are exceptions and must be learned as they are.
