лазурен

Etymology

From лазур (lazur, “clear sky”) + -ен (-en), from Latin lazurium (“bright sky”), itself borrowed from Arabic لَازَوَرْد (lāzaward, “lapis lazuli”), via Russian лазу́рь (lazúrʹ). Akin to English azure, Italian azzurro, Spanish azur where the initial #l- is reinterpreted as the definite article l'- and consequently dropped.
