See also the formations in Italian biancastro (“whitish”), nerastro (“blackish”), French blanchâtre (“whitish”), noirâtre (“blackish”) (with the suffixes -astro and -âtre deriving from Latin -astrum, accusative singular of -aster).

köken: Dissimilation of *caeluleus, derived from caelum (“sky, heaven”) + -uleus (diminutive suffix). However, in Classical Latin the word is attested as denoting the color of the rainy sky and that of deep water, and was on the whole associated with water.

köken: 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.
