Where it comes from

Learned borrowing from Late Latin parenthesis (“rhetorical device where an aside or example is included”), borrowed from Koine Greek πᾰρένθεσῐς (părénthesĭs, “insertion; putting in beside, injection; (grammar) parenthesis”), from Ancient Greek πᾰρεντῐ́θημῐ (părentĭ́thēmĭ) + -σις (-sis), from Ancient Greek πᾰρᾰ- (pără-, prefix meaning ‘beside’) (ultimately from Proto-Indo-European *preh₂- (“before, in front”) and/or from its etymon *per- (“before, in front”)) + ἐν (en, “at; in; on”) (from Proto-Indo-European *h₁én (“in”)) + θέσῐς (thésĭs, “arrangement, placement, setting”) (from τῐ́θημῐ (tĭ́thēmĭ, “to place, put, set”) (ultimate from Proto-Indo-European *dʰeh₁- (“to do; to place, put”)) + -σῐς (-sĭs, suffix forming abstract nouns or nouns of action, process, or result)), modelled after Koine Greek πᾰρεντῐ́θημῐ (părentĭ́thēmĭ, “to put in beside; to mix up”).

The plural is also a learned borrowing from Late Latin parenthesēs.
