The nasal vowels are written with digraphs: ⟨in⟩, ⟨ẹn⟩, ⟨an⟩, ⟨ọn⟩, ⟨un⟩, unless they come after ⟨n⟩. Long vowels are written double, as in dáadáa (transl. fine, okay). The high and low tones are written with acute and grave accents (á, à), while mid tone is unmarked (a), except for disambiguation on a nasal (n̄, etc.). Combinations of these tones produce falling and rising tones, written e.g. â, ǎ when they are combined on a single vowel letter. These may appear on nasal consonants as well, as in ńkọ́ (how...?), nǹkan (things). An apostrophe may be used to mark an elided sound, at the choice of the writer, as in ń'lé (transl. at home), from ní ilé, but sọ́dọ̀ (transl. to a place), from sí ọ̀dọ̀. When n is a syllable of its own before a vowel, as in n ò lọ (transl. I didn't go), it is pronounced [ŋ̍] (plus tone).

In older signage, ⟨C⟩ may be seen for current ⟨Sh⟩.
