Turkish Future Tense: The -acak / -ecek Suffix
How the Turkish future -acak / -ecek works — the two-way vowel harmony that picks between them, the -y- buffer after a vowel-final stem, the final k that softens to ğ in geleceğim, the person endings, and the negative gelmeyecek.

The future tense says what will happen — an intention, a prediction or a promise — and its suffix -acak or -ecek is chosen by the last vowel of the verb stem.
What the future tense does
The suffix goes straight onto the verb stem: gelecek is "he will come" and bakacak "he will look". Nothing else is needed — no auxiliary verb, and no separate word standing in for "will".
One suffix covers what English divides between "will" and "going to": a decision already taken and a flat forecast come out the same way. And the suffix has only two vowel shapes, -acak and -ecek.
Vowel harmony picks the ending
The suffix vowel copies the front or back quality of the stem's last vowel. Front vowels — e, i, ö, ü — take -ecek, so gel gives gelecek. Back vowels — a, ı, o, u — take -acak, so bak gives bakacak.
| Last stem vowel | After a consonant | After a vowel |
|---|---|---|
| e · i · ö · ü | -ecek | -yecek |
| a · ı · o · u | -acak | -yacak |
Only the front or back quality of that vowel counts here; rounding plays no part. The stem gör of görmek, "to see", carries the rounded front vowel ö and still takes plain -ecek — which is why the suffix has two vowel shapes rather than four.
The person endings
A person ending attaches after the future suffix, so a full form runs stem + future + person. geleceğim is "I will come" and geleceğiz "we will come"; the bare gelecek, carrying no ending at all, is the third person, "he will come". The endings are the set built on the personal pronouns — -im, -sin, -iz, -siniz, -ler.
- geleceğim — I will come
- geleceksin — you will come
- gelecek — he, she or it will come
- geleceğiz — we will come
- geleceksiniz — you will come (plural or polite)
- gelecekler — they will come
| Turkish | Parts | English |
|---|---|---|
| geleceğim | gel + eceğ + im | I will come |
| gelecek | gel + ecek | he, she or it will come |
| geleceğiz | gel + eceğ + iz | we will come |
The final k softens before a vowel
A person ending that begins with a vowel softens the k at the end of the suffix to a soft g. On its own gelecek keeps that k; add -im and it becomes geleceğim, and -iz gives geleceğiz the same way.
Endings that begin with a consonant leave the k standing: geleceksin and gelecekler hold on to it, because no vowel ever meets it there.
| Turkish | Parts | English |
|---|---|---|
| geleceğim | gel + eceğ + im | I will come |
| geleceğiz | gel + eceğ + iz | we will come |
Four worked forms
Read each one as a settled plan or a prediction. Between them they show both vowel shapes on a stem that ends in a consonant, and both again on a stem that ends in a vowel, where the buffer -y- steps in.
| Turkish | Parts | English |
|---|---|---|
| gelecek | gel + ecek | he will come |
| bakacak | bak + acak | he will look |
| okuyacak | oku + y + acak | he will read |
| bekleyecek | bekle + y + ecek | he will wait |
Intentions, predictions and promises
The future presents an event as coming fact: a decision the speaker has already taken, a forecast about what lies ahead, a commitment offered as something that will simply happen. The same gelecek can be a firm plan or a neutral prediction, and context tells the two apart.
A time word sits with it naturally and pins down when. yarın is "tomorrow", and yarın gelecek is "he will come tomorrow".
| Turkish | Parts | English |
|---|---|---|
| gelecek | gel + ecek | he will come |
The negative future
To say something will not happen, the negative suffix goes between the stem and the future suffix. It ends in a vowel, so the buffer -y- comes in after it, and the two shapes surface as -meyecek on a front stem and -mayacak on a back one: gelmeyecek is "he will not come" and yapmayacak "he will not do".
| Turkish | Parts | English |
|---|---|---|
| gelmeyecek | gel + me + y + ecek | he will not come |
Frequently asked questions
- What does the Turkish -acak / -ecek suffix mean?
- It marks the future tense — what is going to happen, whether that is an intention the speaker has already formed, a prediction or a promise. gelecek is "he will come" and bakacak "he will look". The vowel harmonises: front stems take -ecek, back stems -acak.
- When is the future -acak and when is it -ecek?
- It depends on the last vowel of the stem. Front vowels — e, i, ö, ü — take -ecek, as in gelecek; back vowels — a, ı, o, u — take -acak, as in bakacak. Rounding plays no part, so there are just these two shapes. After a stem that ends in a vowel a buffer -y- appears, giving -yecek and -yacak: okuyacak, bekleyecek.
- Why is it geleceğim and not gelecekim?
- Because the k that ends the future suffix softens to a soft g whenever a vowel-initial ending follows it. gelecek plus -im is geleceğim, never gelecekim. The bare gelecek and the consonant-initial geleceksin keep their k, since no vowel meets it there.
- How do you make the Turkish future negative?
- Put the negative suffix between the stem and the future suffix. It ends in a vowel, so the buffer -y- comes in after it and the endings surface as -meyecek on a front stem and -mayacak on a back one: gelmeyecek is "he will not come" and yapmayacak "he will not do".
