Etymology tree
Forms
expers (genitive expertis); third-declension one-termination adjective[1] Turpilius has the form expars.[2]
Etymology
It is formed from Latin ex- (“out of, without”) + pars (“part, share”).[2][1][3] De Vaan traces ⟨pars⟩ to Proto-Italic *parti- (“part”) and reports Schrijver's view that it was made from the present stem of pariō (“to bring forth”), first meaning “lot, portion”.[3]
Earliest recorded meaning
De Vaan and Köbler give Plautus as its first author.[3][4] In the Amphitruo Sosia complains that his master is himself free of toil (labōris expers).[2]
Semantic evolution
It is having no share, as Accius' exile “without hope, without a share”, and so lacking or deprived of something, as Terence's girl who must not be left without a share of the family property.[2][5] It also means taking no part in a matter (Cicero), free or immune from something, and in Pliny the Elder unused to, without experience of.[2] It usually takes the genitive, less often the ablative.[2]
Church Latin glosses it “lacking in, destitute”,[6] and medieval Latin also used it for expertus, “experienced”.[7]
