"act or fact of sharing or partaking in common with another or others; act or state of receiving or having a part of something," late 14c., participacioun, from Old French participacion (13c.) and directly from Late Latin participationem (nominative participatio) "partaking," noun of action from past-participle stem of Latin participare "participate in, share in, partake of; to make partaker, to share, impart," from particeps (genitive participis) "partaker, comrade, fellow soldier," also, as an adjective, "sharing, partaking," from pars (genitive partis) "a part, piece, a division" (from PIE root *pere- (2) "to grant, allot") + -cip-, weak form of stem of capere "to take," from PIE root *kap- "to grasp."

participatory (adj.)

"sharing, having a share or part in common with others," 1833, from participate + -ory. Participatory democracy is attested by 1965, a term from student protests and mass demonstrations, contrasted with representative democracy. The formulation of the idea, if not the phrase, seems to trace to U.S. progressive political writer Walter Lippmann (1889-1974).

participle (n.)

late 14c., in grammar, "a noun-adjective, a word having the value of an adjective as a part of speech but so regularly made from a verb and associated with it in meaning and construction as to seem to belong to the verb," from Old French participle in the grammatical sense (13c.), a variant of participe, and directly from Latin participium, literally "a sharing, partaking," also used in the grammatical sense, from particeps "sharing, partaking" (see participation). In grammatical sense, the Latin translates Greek metokhē "sharer, partaker," and the notion is of a word "partaking" of the nature of both a noun and an adjective.
