Etymology
It is inherited from Proto-Italic *sem-g-lo-, from Proto-Indo-European *s(e)m-gʰ- (“single”): Meiser explains it as containing a distributive particle *-gʰ-, later suffixed with *-lo-.[1][2] The root is that of semel “once” and simplex “simple”.[2][3][4] De Vaan dismisses an older derivation as *sem-ǵno- from the root of “to be born”.[1]
Earliest recorded meaning
De Vaan dates it from Plautus, whose character speaks of men who eat one meal a day.[1][2] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
As a distributive it meant one apiece, one each, as Cicero's twelve acres to each man.[2][3] It also meant taken separately, individual, as Cicero's arts that each defend themselves, single as opposed to groups, isolated, and single in number.[2] Lewis and Short note that the singular is only ante- and post-classical.[6] The feminine singulae was the name of a coin, half a libella.[2]
In Medieval Latin it meant every.[7] Through Old French sengle the singular singulus is the source of English single, recorded in the early 14th century.[4]
