what is it?
Turkish has no standalone verb meaning «to be» in the present tense — the copula is a suffix. In the past, however, it surfaces as a distinct suffix attached directly to a nominal predicate (a noun, adjective, or adverbial). There are two past copulas: -(y)DI, which marks a past state the speaker witnessed or knows directly (e.g. hastaydım — «I was ill»), and -(y)mIş, which marks a past state reported second-hand or inferred (e.g. hastaymış — «she was apparently ill»). Both suffixes carry their own set of personal endings and follow standard four-way vowel harmony. They are not the same as the verbal past tense suffix -DI added to verb stems.
when to use it?
Direct past states with -(y)DI. Use this when you personally witnessed or experienced the state: a past identity, quality, location, or condition. The speaker has first-hand knowledge.
Past existence with vardı / yoktu. The existence words var («there is») and yok («there is not») take the same -(y)DI suffix to give vardı («there was») and yoktu («there was not»). These are fixed third-person forms and do not change for person.
Reported or inferred past states with -(y)mIş. Use this when you did not witness the state yourself — you heard it from someone else, read it, or are inferring it from evidence. It is often translated as «apparently», «reportedly», or «I hear that».
formation
Both suffixes attach to the predicate and then take personal endings. The key rule: if the predicate ends in a vowel, insert a buffer -y- before the suffix. If it ends in a consonant, attach directly. The vowel in both suffixes follows four-way harmony (I = ı / i / u / ü).
-(y)DI takes Group 1 personal endings (the same set used with the verbal -DI past): -m, -n, -(zero), -k, -nIz, -lAr.
| person | stem + suffix | meaning |
|---|---|---|
| ben | hasta-y-dı-m | I was ill |
| sen | hasta-y-dı-n | you were ill |
| o | hasta-y-dı | he/she/it was ill |
| biz | hasta-y-dı-k | we were ill |
| siz | hasta-y-dı-nız | you (pl.) were ill |
| onlar | hasta-y-dı-lar | they were ill |
Consonant-final stem example: öğrenci ends in a vowel → öğrenciydim. evde ends in a vowel → evdeydim. doktor ends in a consonant → doktorduk (we were doctors).
-(y)mIş takes Group 2 personal endings (the same set used with the -mIş perfect): -Im, -sIn, -(zero), -Iz, -sInIz, -lAr.
| person | stem + suffix | meaning |
|---|---|---|
| ben | hasta-y-mış-ım | I was apparently ill |
| sen | hasta-y-mış-sın | you were apparently ill |
| o | hasta-y-mış | he/she/it was apparently ill |
| biz | hasta-y-mış-ız | we were apparently ill |
| siz | hasta-y-mış-sınız | you (pl.) were apparently ill |
| onlar | hasta-y-mış-lar | they were apparently ill |

common pitfalls
Attaching the verbal -DI directly to a nominal. The verbal past suffix goes on verb stems only. On a nominal predicate you need the copula form with its buffer: ✗ hastadım → ✓ hastaydım. Without the -y- buffer the form is ungrammatical.
Using the wrong personal-ending group. -(y)DI takes Group 1 endings (-m, -n, -k, -nIz, -lAr), not Group 2. A common mistake is to add a Group 2 first-person ending: ✗ hastaydıyım → ✓ hastaydım. Reserve Group 2 endings for -(y)mIş.
Forgetting the -y- buffer after a vowel-final stem. Whenever the predicate ends in a vowel, the buffer consonant -y- is obligatory before both -(y)DI and -(y)mIş: ✗ hastadı → ✓ hastaydı. Consonant-final stems (e.g. yorgun) attach the suffix directly without a buffer.
