Saying "Can't" in Turkish: -(y)AmA-
Turkish builds “can” by stacking the auxiliary verb bilmek (“to know”) onto a stem - gel-ebil-ir-im, “I can come.” The natural guess for “can’t” is to just add “not” onto that same structure. Turkish doesn’t do that. Instead it drops bil- entirely and uses its own dedicated negative suffix, -(y)eme-/-(y)ama-, straight on the verb stem.
What this suffix does
-(y)eme-/-(y)ama- expresses inability - the negative counterpart to everything the ability suffix -ebilmek/-abilmek covers:
- Physical or learned inability - Ben yüzemem. - I can’t swim.
- Impossibility - O bugün gelemez. - He/she can’t come today.
- Lack of permission - Buraya oturamazsın. - You can’t sit here.
- Inability in the past - Dün erken kalkamadım. - I wasn’t able to get up early yesterday.
The most common beginner mistake is reaching for gelebilmem as the negative of gelebilirim. That form doesn’t exist in standard Turkish for this meaning - the auxiliary bil- simply isn’t there in the negative at all.
Forming it
The suffix follows the same two-way vowel harmony as its affirmative counterpart - front/back only, based on the stem’s last vowel:
| Last vowel of the stem | Negative ability suffix |
|---|---|
| e, i, ö, ü (front) | -eme- |
| a, ı, o, u (back) | -ama- |
A vowel-final stem takes a buffer -y- before the suffix, exactly as with -ebilmek/-abilmek: oku- (read) gives okuyama-, and bekle- (wait) gives bekleyeme-. A consonant-final stem needs no buffer: yap- (do) → yapama-.
Where the two suffixes really part ways is the personal endings. -ebilmek/-abilmek always takes the regular aorist -ir before the personal ending. -(y)eme-/-(y)ama- instead follows Turkish’s own irregular negative-aorist pattern, where the marker -mez loses its z in the first person only:
| Person | Ending | gel- (to come) | yap- (to do) |
|---|---|---|---|
| ben (I) | -m | gelemem | yapamam |
| sen (you) | -zsin | gelemezsin | yapamazsın |
| o (he/she/it) | -z | gelemez | yapamaz |
| biz (we) | -yiz | gelemeyiz | yapamayız |
| siz (you, pl./formal) | -zsiniz | gelemezsiniz | yapamazsınız |
| onlar (they) | -zler | gelemezler | yapamazlar |
Notice that ben and biz drop the -z- (gelemem, gelemeyiz), while sen, o, siz, and onlar all keep it (gelemezsin, gelemez, gelemezsiniz, gelemezler). This isn’t specific to the ability suffix - ordinary negative-aorist verbs show the exact same first-person z-drop (gelmem, gelmezsin, gelmeyiz…), and -(y)eme-/-(y)ama- simply inherits that irregularity because it’s built on the same negative-aorist machinery, minus bil-.
Exceptions worth knowing
The z-drop is a fixed quirk of the negative aorist, not something specific to this suffix. Any verb’s ordinary negative-aorist paradigm shows the same pattern - bilmem (I don’t know), bilmeyiz (we don’t know) versus bilmezsin, bilmez, bilmezsiniz, bilmezler - so once you’ve learned it once, it applies everywhere the negative aorist appears, ability suffix or not.
-(y)eme-/-(y)ama- isn’t locked to the aorist-style present - it layers onto other tenses too, shifting the meaning from “can’t” to “wasn’t able to” or “won’t be able to.” Bu akşam gelemeyeceğim.
- I won’t be able to come this evening. (negative ability + future -ecek, not the bare negative-aorist shape) The plain present-tense forms above are by far the most frequent, which is why this lesson focuses on them, but the suffix itself combines with past and future tense markers the same way any verb stem would.
A second, separate meaning layer on top of inability is impossibility or unlikelihood, much like English “can’t” sometimes means “surely isn’t.” Bu kadar erken bitmiş olamaz. - It can’t possibly have finished this early. The grammar doesn’t change; only the real-world reading shifts from physical inability to a judgment about likelihood.
Examples
- Ben yarın gelemem. - I can’t come tomorrow.
- Sen bu şarkıyı söyleyemezsin. - You can’t sing this song.
- O beş dil konuşamaz. - He/she can’t speak five languages.
- Biz bu akşam erken çıkamayız. - We can’t leave early this evening.
- Siz bu soruyu cevaplayamazsınız. - You can’t answer this question.
- Onlar hafta sonu bize gelemezler. - They can’t come to our place this weekend.
Every sentence keeps the same shape - stem, negative ability suffix, personal ending - with the z-drop appearing only in the ben and biz rows, and vowel harmony changing -eme-/-ama- depending on the stem.

Frequently asked questions
How do I say "I can't" in Turkish?
Attach -eme or -ama (chosen by vowel harmony) directly to the verb stem, then the personal ending - no aorist -ir and no trace of bilmek survive. Gelemem means "I can't come," from gel- (come) + -eme- + -m. Note it isn't gelebilmem; Turkish never keeps bil- in the negative.
Why is it gelemem but gelemezsin, not gelemezim?
The suffix -(y)AmA- is built on Turkish's irregular negative aorist, where the marker -mez loses its z in the first person: gelemem (I can't) and gelemeyiz (we can't) drop the z, while gelemezsin (you can't), gelemez (he/she/it can't), gelemezsiniz, and gelemezler keep it. This same quirk shows up in ordinary negative-aorist verbs like gelmem/gelmezsin, so it isn't unique to the ability suffix.
What is the difference between -(y)Abilmek and -(y)AmA- in Turkish?
-(y)Abilmek (e.g. gelebilirim, "I can come") is the affirmative ability suffix, built from the verb stem plus the auxiliary bilmek ("to know"). Its negative is not formed by adding "not" onto that same auxiliary - Turkish uses a separate, shorter suffix, -(y)AmA- (e.g. gelemem, "I can't come"), that deletes bil- altogether rather than negating it.
