Од the Стари Јерменски digraph ու (u) representing [u], composed of ո (o) + ւ (w). Some have contended that Стари Јерменски ու (u) was a diphthong, but this is incorrect: representing the monophthong [u] with a digraph is modelled on Антички Грчки ου (ou) pronounced as [u]. Compare Старословенски оу (u).
- The 34th letter of Арамејско писмо according to Reformed Orthography. Represents close back rounded vowel: [u]. Transliterated as u (sometimes as ow).
- Considered a separate letter after the spelling reform of the Armenian language of 1922–1924. The Traditional Armenian orthography treats ու as a simple digraph of ո (o) + ւ (w) and not as a separate letter.
- When used in sentence case, such as Ուրարտու (Urartu), the capital form of the letter is Ու. However, in all caps text it is ՈՒ, e.g. ՈՒՇԱԴՐՈՒԹՅՈՒՆ (UŠADRUTʿYUN).

- ես ու դու ― es u du ― me and you
Generally used to link two things in close relation, such as in English you and I or in the sense of combining two clauses of close relation while deemphasizing their relationship. In English, this would generally be done by combining predicates, as in I went to the store and bought ice cream. It is never used as a conjunction in the fashion of և (ew), which is used as a coordinating conjunction between two independent clauses, as in I went to the store, and I bought ice cream.
