The orthography of Ottoman Turkish is complex, as many Turkish sounds can be written with several different letters. For example, the phoneme /s/ can be written as , , or . Conversely, some letters have more than one value: "k" may be /k/, /ɡ/, /n/, /j/, or /ː/ (lengthening the preceding vowel; modern ğ), and vowels are written ambiguously or not at all. For example, the text "kwrk" can be read as /ɡevrek/ 'biscuit', /kyrk/ 'fur', /kyrek/ 'shovel', /kœryk/ 'bellows', /ɡœrek/ 'view', which in modern orthography are written "gevrek", "kürk", "kürek", "körük", "görek".
