Yu, from the Alphabet Book оf the Red Army Soldier (1921) Yu or Ju (Ю ю; italics: Ю ю or Ю ю; italics: Ю ю) is a letter of the Cyrillic script used in East Slavic and Bulgarian alphabets.
In English, Yu is commonly romanized as ⟨yu⟩ or ⟨ju⟩. In turn, ⟨ю⟩ is used, where available, in transcriptions of English letter ⟨u⟩ (in open syllables), and also of the ⟨ew⟩ digraph. The sound [y], like ⟨u⟩ in French and ⟨ü⟩ in German, may also be approximated by the letter ⟨ю⟩.
