Lje (Љ љ; italics: Љ љ) is a letter of the Cyrillic script.
Lje represents a palatal lateral , a sound similar (but not identical) to the palatalized alveolar lateral, which is in some languages represented by the digraph ⟨ль⟩ and pronounced like the in "million".
Lje is a ligature of ⟨ л⟩ and ⟨ ь⟩. It was invented by Vuk Stefanović Karadžić for use in his 1818 dictionary, replacing the earlier digraph ⟨ль⟩. It corresponds to the digraph in Gaj's Latin alphabet for Serbo-Croatian.
It is today used in Macedonian, variants of Serbo-Croatian when written in Cyrillic ( Bosnian, Montenegrin and Serbian), and Itelmen.
