Pronunciation

Forms

mollasse (plural mollasses)[2] Middle French mollace (Amyot).[3]

Etymology

It is formed from French mou + -asse, from the old form mol of the adjective and the pejorative suffix.[4][5][1][3][6] The adjective mou is mollis.[6]

The Grand Robert and the Petit Robert also allow a borrowing from the Italian word molaccio, and Picoche gives that as the source;[1][7][8] the TLFi and Rey find that hypothesis unnecessary.[4][5] Littré compares the Genevan form mollache.[3]

Earliest recorded meaning

It is first found in 1551, in Du Parc Champenois's translation of the Philosophie d'amour of Léon l'Hébreu, meaning soft and without consistency.[4][5]

Semantic evolution

From 1559 Amyot uses it of people for a lack of energy and liveliness: in his Lives a man goes about trailing his gown d'une allure mollace.[4][3][5] The word has kept both senses, too soft or flabby (of things, flesh, fabric) and listless (of people).[5][3][7]

As a noun for a spineless person it is recorded in the feminine in 1866 (Delvau) and in the masculine in 1869 (Flaubert).[4][5] Its derivatives are mollassement (1582), mollasserie (1838) and the commoner diminutive mollasson (1880).[5][4]

Usage notes

The Grand Robert has a second mollasse (n. f.), a clayey sandstone used for building, now usually spelled molasse; it records pierre molasse from the early 17th century and the noun from the 18th, and explains it either as the adjective used as a noun or as a pejorative form of meulière.[1][7] The GLLF dates it to 1669 and also derives it from mol.[9] Rey thinks it is probably the same word, of Franco-Provençal origin and found in French-speaking Switzerland from the 15th century.[5]
