Word Origin

a prefix appearing in loanwords from Greek, most often attached to verbs and verbal derivatives, with the meanings “at or to one side of, beside, side by side” (parabola; paragraph; parallel; paralysis), “beyond, past, by” (paradox; paragogue); by extension from these senses, this prefix came to designate objects or activities auxiliary to or derivative of that denoted by the base word (parody; paronomasia), and hence abnormal or defective (paranoia), a sense now common in modern scientific coinages (parageusia; paralexia). As an English prefix, para-¹, may have any of these senses; it is also productive in the naming of occupational roles considered ancillary or subsidiary to roles requiring more training, or of a higher status, on such models as paramedical, and paraprofessional: paralegal; paralibrarian; parapolice.

Chemistry. a combining form designating the para (1, 4) position in the benzene ring.

Abbreviation: p-.

Compare meta- (def 4b), ortho- (def 2b).

Also, especially before a vowel, par-.

Origin

< Greek para-, combining form representing pará (preposition) beside, alongside of, by, beyond

para-²

a combining form meaning “guard against,” occurring in loanwords from French, or, via French, from Italian: parachute; parasol.

Origin

< French < Italian para, 3rd singular present of parare to prepare against, ward off < Latin parāre to prepare

para-³

a combining form extracted from parachute, forming compounds denoting persons or things utilizing parachutes or landed by parachute: paradrop; paradoctor; paraglider; paratrooper.
