Pronunciation

Forms

mollir[1]

Etymology

It is formed from French mou + -ir, from the older form mol of the adjective.[2][3][4] Wiktionary allows also a direct origin in Latin molliō (“to soften”),[1] which Littré gives as its source, the Latin verb being from mollis (“soft”).[5]

Earliest recorded meaning

It is first recorded in the second half of the 13th century in a Liège medical text, transitively, meaning “to make soft”.[2][6] The Anglo-Norman Dictionary records it from the middle of the 13th century, meaning to soften or relax.[7]

Semantic evolution

The transitive verb had both a physical sense, “to soften”, and a moral one, “to weaken, make someone yield” (Ronsard, 1555, who in 1552 already wrote mollis un peu le roc de ton courage).[6][2] From 1462 it was also used intransitively, “to become soft”, and in the 17th century “to give way, lack firmness” (Molière, 1669) and “to lose strength, falter” (Boileau, 1683).[2][6]

Sailors used it from 1691 for easing off a taut rope, and later for the wind dying down.[2][5] Familiar usage took it for “to flag, slow down” (1842).[6] It remains less common than its prefixed forms amollir and especially ramollir.[6]
