Forms

rare (plural rares)[1]

Etymology

It is borrowed from Latin rārus (“loose, sparse; few; infrequent; exceptional”),[2][3][1][4] a learned remodelling (Oresme, 1377) of the inherited Old French rer or rere (late 12th century), which was limited to Old French.[2][5][6] Bloch and Wartburg note the inherited adverb rerement in the 12th and 13th centuries.[3]

Rey reports a tentative connection of the Latin adjective with ratis (“raft”), with the idea of an open framework, and a root shared with Lithuanian irti (“to fall apart”), though the link remains vague.[5] Cognate with Old Occitan rar, Spanish raro and Italian raro; the inherited forms are Italian rado and Spanish ralo.[7][8]

Earliest recorded meaning

The inherited rere appears in the late 12th century in the Moralités sur Job in the sense “uncommon, remarkable”: Mult est rere chose….[2][7] The learned rare first appears in Oresme (1377) in the Latin physical sense “not dense, thin”, of water and air.[2][5]

Semantic evolution

Gautier de Coinci (about 1225) has rere for “seldom met with”, and rare takes that sense in Robert Estienne (1539); from 1504–09 it also means “infrequent” of events.[2][5] From the mid-16th century it has the Latin qualitative sense “exceptional” (1553, Olivier de Magny), often with the idea of something precious (livres rares), and, from the 17th century a nuance of oddness (1694, un homme rare).[5][2]

By Latinism it took again the sense “not dense” (1555), whence “thin, sparse” of hair or grass (1636).[5][2] Oiseau rare (1636) is a calque of Horace's rara avis, used figuratively by La Fontaine (1665).[2][5] Chemistry has terres rares (1898) and gaz rares (1916), after English.[2]
