The 'To Be' Suffixes (Copula)

Grammar Rule in 30 Seconds

In Turkish, 'to be' isn't a separate word; it's a suffix attached to the end of a noun or adjective.

  • Use -im/-ım/-um/-üm for 'I am' (e.g., 'Öğrenciyim' - I am a student).
  • Use -sin/-sın/-sun/-sün for 'You are' (e.g., 'İyisin' - You are well).
  • No suffix is needed for 'He/She/It is' (e.g., 'O mutlu' - He/She is happy).
Noun/Adjective + Personal Suffix = 'To Be' Sentence
