Forms

éclaircir[1] Old French esclarcir, from about 1230 also esclaircir.[2][3]

Etymology

It is inherited from Old French esclarcir, inherited from Vulgar Latin *exclaricīre, a remaking of *exclaricō, an intensive of Imperial Latin clāricō (“to shine brightly”), itself from clārus (“clear, bright”).[2][4][3][5] The form in ⟨-īre⟩ was modelled on *exclāriō, the source of éclairer and of Old French esclargier, already in the Chanson de Roland.[2][6] About 1230 the spelling esclaircir appears, under the influence of clair.[3][6] Bloch and Wartburg note that in these verbs the prefix ex- expresses coming out of darkness into light.[6]

Littré compares Occitan esclarzir, Catalan esclarir, Spanish esclarecer and Portuguese esclarecer.[7]

Earliest recorded meaning

About 1130, in Li vers del Juise, esclarcir is said of daylight appearing and shining and of the sun shining brightly.[2][3]

Semantic evolution

Around 1165 resclarcir meant “make bright”, and about 1393 the Ménagier de Paris uses the verb for clearing wine.[2] Applied to abstract things, it meant “throw light on” (about 1200) and “bring to light” (1210–1230), then “make clear, sort out” in Beaumanoir's Coutumes de Beauvaisis (1283).[2][3]

In the concrete sense of making something less dense, Froissart uses it of the ranks of an army in the 14th century and Montaigne of branches in 1580.[2][3] Éclaircir quelqu'un “inform someone” (17th century) has aged, and s'éclaircir avec quelqu'un “explain oneself” is gone; these senses live on in éclaircissement.[3] In African French the pronominal verb is used for lightening one's skin.[3]
