Verb Personal Endings: The Two Sets | Turkish Grammar

Turkish does not need a separate subject pronoun the way English does. Instead, a small suffix at the very end of the verb tells you who is doing the action — geliyorum already means "I am coming," with no ben required. These subject-marking suffixes are called personal endings, and the single most important thing to learn about them is that there are two different sets of them. Master the split between these two families and you have unlocked the skeleton of every conjugation in the language.

The two sets at a glance

Person	Type 1 — the -(y)Im set	Type 2 — the -m set
1sg (I)	-(y)Im geliyorum	-m geldim
2sg (you)	-sIn geliyorsun	-n geldin
3sg (he/she/it)	-Ø geliyor	-Ø geldi
1pl (we)	-(y)Iz geliyoruz	-k geldik
2pl (you-pl/formal)	-sInIz geliyorsunuz	-nIz geldiniz
3pl (they)	-lAr geliyorlar	-lAr geldiler

Read the two columns side by side and the pattern jumps out. The endings agree on the third person (both are zero in the singular and -lAr in the plural), but they differ sharply in the first and second persons. Type 1 uses longer, vowel-based endings (-Im, -Iz); Type 2 uses short consonant endings (-m, -k). That contrast — especially in the I and we forms — is what you are really learning to control.

Which set does a verb take?

This is the rule that governs everything: the personal ending is chosen by the tense suffix that comes immediately before it. The verb stem has no say; the tense decides which family of endings clicks on at the end.

The Type 1 set attaches after the "imperfective-ish" tenses and on nominal predicates:

present continuous -Iyor → geliyorum (I am coming)
aorist -Ir → gelirim (I come / I'll come)
future -(y)AcAK → gelecekim → geleceğim (I will come)
evidential past -mIş → gelmişim (I apparently came)

The Type 2 set attaches after just two suffixes — but two extremely common ones:

definite past -DI → geldim (I came)
conditional -sA → gelsem (if I came / were I to come)

Şu an okula gidiyorum, on dakikaya orada olurum.

I'm on my way to school right now, I'll be there in ten minutes.

Dün akşam çok geç yattım, bu yüzden bugün çok yorgunum.

I went to bed very late last night, so I'm really tired today.

In gidiyorum the tense is the present continuous -iyor, so the I ending is the Type-1 -um. In yattım "I went to bed" the tense is the definite past -tı, so the I ending is the Type-2 -m. Same speaker, same "I," two different endings — and the only reason is which tense suffix sits in front of the personal ending.

💡

You never choose a personal ending in isolation. First identify the tense suffix on the verb, then attach the set that tense governs: -Iyor / -Ir / -(y)AcAK / -mIş take Type 1, while the past -DI and the conditional -sA take Type 2.

The 1sg split is the cleanest tell

If you remember just one diagnostic, make it the first-person singular. After almost every tense, "I" is -Im (Type 1): geliyorum, gelirim, gelecekim, gelmişim. But after the definite past and the conditional, "I" collapses to a bare -m (Type 2): geldim, gelsem.

Bu şarkıyı her duyduğumda seni hatırlarım.

Every time I hear this song, I remember you.

Seni aradım ama telefonun kapalıydı.

I called you, but your phone was off.

Hatırlarım "I remember" is built on the aorist -ır, so its I is -ım (Type 1). Aradım "I called" is built on the past -dı, so its I is the short -m (Type 2). When you are unsure whether a verb form is "past-like," check what its I looks like: a full -Im means you are not in the past/conditional family; a bare -m means you are.

The second person is just as telling: -sIn vs -n. Geliyorsun "you are coming" (Type 1) versus geldin "you came" (Type 2). The Type-2 second-person is a single -n glued straight onto the tense vowel.

Sen her zaman doğru olanı söylersin, bu yüzden sana güveniyorum.

You always say the right thing, that's why I trust you.

Bana neden hiç haber vermedin? Çok merak ettim.

Why didn't you let me know at all? I was really worried.

💡

When you're unsure which set a verb form belongs to, look at the "I" form. A full -Im (gelirim, geleceğim) means you're in the Type-1 family; a bare -m (geldim, gelsem) means you're in the past/conditional Type-2 family. The 1sg is the single most reliable diagnostic.

Both sets harmonise

Every ending in both columns is written with capital letters precisely because its vowels obey vowel harmony. The I in -Im / -sIn / -Iz / -sInIz is a four-way vowel (i / ı / u / ü), and the A in -lAr is two-way (e / a). So Type 1 I is -im after a front-unrounded stem (gelirim) but -um after a rounded one (geliyorum), -ım after a back-unrounded one (alır*ım), and -üm* after a front-rounded one (*görürüm*).

Type 2 harmonises too, though its single-consonant endings (-m, -n, -k) carry no vowel of their own — the harmonising vowel lives in the tense suffix in front of them (geldim vs aldım, the i/ı difference belonging to the past suffix -DI).

Akşam yemeğini hazırlıyorum, yarım saate hazır olur.

I'm making dinner, it'll be ready in half an hour.

Bütün gün seni düşündüm, umarım iyisindir.

I thought about you all day, I hope you're well.

The buffer y in Type 1

Two Type-1 endings — -(y)Im and -(y)Iz — start with a vowel, and Turkish does not allow two vowels to collide. When the tense suffix in front of them already ends in a vowel, a buffer y slips in: future gelecek + -im gives geleceğim (here the k also softens, see stem changes), but on a vowel-final base you hear the buffer clearly — uyuyacak "will sleep" → uyuyacağ*ım. On nominal predicates the buffer is obvious: öğretmen "teacher" + -im = öğretmenim (no buffer needed after a consonant), but *hasta "ill" + -(y)Im = *hastayım* "I am ill." Type 2 never needs a buffer, because its endings begin with consonants.

Ben de öğretmenim, on yıldır bu okuldayım.

I'm a teacher too, I've been at this school for ten years.

Common mistakes

❌ Dün seni aradıyım.

Incorrect — after the past -DI you use the Type-2 -m, not the Type-1 -Im: aradım.

✅ Dün seni aradım ama açmadın.

I called you yesterday but you didn't pick up.

❌ Geldim çünkü çok geliyordum yorgun.

Incorrect — the Type-1 -um belongs only after -Iyor etc.; with the past, 'I came' is geldim.

✅ Geldim çünkü seni çok özledim.

I came because I missed you a lot.

❌ Yarın geleceğim mı?

Incorrect — Type-1 1sg is -(y)Im, giving geleceğim; the question particle and harmony are fine, but never *geleceğmim or a Type-2 -m here.

✅ Yarın size geleceğim, saat kaçta uygun?

I'll come to your place tomorrow, what time works?

❌ Biz dün sinemaya gittiz.

Incorrect — after the past, 'we' is the Type-2 -k: gittik, not the Type-1 -iz.

✅ Biz dün sinemaya gittik, film harikaydı.

We went to the cinema yesterday, the film was great.

The deepest error is mixing the families — putting a Type-1 ending after a past or conditional stem (aradıyım, gittiz). It happens because learners memorise geliyorum first and then over-apply its -um/-iz everywhere. The fix is the 1sg diagnostic: if the tense is the definite past -DI or the conditional -sA, the I must be a bare -m and the we a bare -k.

Key takeaways

Turkish has two sets of personal endings; Type 1 (-(y)Im, -sIn, -Ø, -(y)Iz, -sInIz, -lAr) and Type 2 (-m, -n, -Ø, -k, -nIz, -lAr).
The tense suffix chooses the set. Type 1 follows -Iyor, -Ir, -(y)AcAK, -mIş and nominal predicates; Type 2 follows the definite past -DI and the conditional -sA.
The 1sg split is the clearest tell: -Im almost everywhere (geliyorum, gelirim, geleceğim) but bare -m after past/conditional (geldim, gelsem).
Both sets harmonise; Type 1's vowel-initial endings take a buffer y after a vowel (hastayım, uyuyacağım).
The signature beginner error is mixing the sets (geldiyim); always read the tense first, then attach the set it governs.
