Forms

obsolète (plural obsolètes)[1] Earlier spellings obsolet (1596, 1677) and obsolete (1750).[2][3]

Etymology

It is borrowed from Latin obsolētus (“gone out of fashion, worn out”), borrowed several times: as ⟨obsolet⟩ in 1596 (Hulsius) and in 1677, when Miège glossed the English word obsolete, then as ⟨obsolete⟩ in 1750 (Prévost).[2][3][4] The Latin word is the past participle, used as an adjective, of obsolēscō (“to go out of use”).[2][3]

The origin of the Latin verb is obscure: Rey finds neither an analysis with olēscō (“to grow”) nor one as an inchoative of soleō (“to be accustomed”) satisfactory, and supposes contamination with exolēscō (“to fade, fall into disuse”).[3] Littré had derived it from ob and the verb “to be accustomed”.[5]

Earliest recorded meaning

It is first recorded in 1596, in Hulsius, as obsolet “out of use”.[2][6]

Semantic evolution

The word stayed rare: the Grand Robert dates the spelling obsolète from Prévost in 1755 and notes that it was taken up again in the 19th century, Littré treating it as a neologism of some grammarians for words out of use.[7][5] It belonged to a literary or archaizing style, mainly in religion and linguistics, and was used jokingly of people.[3] From 1868 naturalists used it for markings that are barely visible.[3][6]

In the 20th century the economic sense “superseded” came from the English word obsolete; the present uses extend it.[3] The same English influence brought obsolescence (1955, R. Barre) and obsolescent (1960).[3]
