Kişi zamirleri and the 'to be' endings
Turkish has six personal pronouns: ben (I), sen (you, sg.), o (he/she/it), biz (we), siz (you, pl./formal), onlar (they). But here's the surprise — Turkish doesn't use a separate verb 'to be'. Instead, you stick a personal ending right onto the noun or adjective. Ben öğretmenim = 'I am a teacher' (literally 'I teacher-am'). The ending -im says 'I am'. Even more startling: you can drop the pronoun, because the ending already tells you who. Öğretmenim alone = 'I am a teacher'.
The six pronouns
ben = I. sen = you (one person, casual). o = he, she, or it — Turkish has no grammatical gender, so the same word covers all three. biz = we. siz = you (plural, or polite singular — like French vous). onlar = they. Use siz with strangers, elders, and your boss; sen is for friends, family, kids, and peers.
The 'to be' endings
Six endings, one for each pronoun, attached to the predicate noun or adjective. With öğretmen (teacher): Ben öğretmenim (I am), Sen öğretmensin (you are), O öğretmen (he/she/it is — no ending in modern speech, though formal writing adds -dir), Biz öğretmeniz (we are), Siz öğretmensiniz (you all are / you formally are), Onlar öğretmenler (they are — uses the plural marker). The endings are -im, -sin, -, -iz, -siniz, -ler.
Vowel harmony preview
These endings change shape based on the last vowel of the word. After öğretmen (front, unrounded vowel e) we get -im, -sin, -iz, -siniz. After doktor (back, rounded o) the vowel flips: doktorum, doktorsun, doktoruz, doktorsunuz. The four possible vowels for the personal endings are i, ı, u, ü — chosen to match the last vowel of the stem. We'll cover this systematically in the next lesson, so for now just notice that vowels echo.
Dropping the pronoun
Because the ending already shows who, the pronoun is optional and often dropped. Öğrenciyim = 'I'm a student'. Türksün? = 'Are you Turkish?'. Amerikalıyız = 'We're American'. You add the pronoun back when you want emphasis or contrast: BEN öğrenciyim, SEN öğretmensin = 'I'm a student, YOU are a teacher'.
The buffer y
When the noun ends in a vowel, a buffer y slips in to keep two vowels apart. Türk (Turk, ends in consonant) → Türküm (I am Turkish). But Amerikalı (American, ends in vowel) → Amerikalıyım (I am American). Same idea with Türkiyeliyim (I'm from Turkey). Just remember: vowel + ending starting with vowel = insert y.
