单词 propagation
释义

propagationn.

Brit. /ˌprɒpəˈɡeɪʃn/, U.S. /ˌprɑpəˈɡeɪʃ(ə)n/
Forms: late Middle English propagacioun, late Middle English propagacyon, late Middle English–1500s propagacion, 1500s propagatioun (Scottish), 1500s– propagation, 1600s propogation (probably transmission error).
Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French propagation; Latin propāgātiōn-, propāgātiō.
Etymology: < Middle French propagacion, propagation (French propagation ) descendant (13th cent. in Old French in an isolated attestation), production of offspring, procreation (c1380), race, generation (end of the 15th cent. or earlier) and its etymon classical Latin propāgātiōn-, propāgātiō reproduction (of plants) by layers of slips, continuation of a family by procreation, transmission to posterity, action of extending in space or time, prolongation, in post-classical Latin also offspring, progeny (12th cent. in a British source) < propāgāt- , past participial stem of propāgāre (also prōpāgāre ) propagate v. + -iō -ion suffix1. Compare Catalan propagació (end of the 14th cent.), Spanish propagación (second half of the 15th cent.) , Italian propagazione (1363).Many specialized senses of the English word appear not to be paralleled in French until later than in English, e.g. sense 2 in 1688 (with reference to the spreading of a religion; 1690 with reference to the dissemination of ideas or practices in general), sense 6 in 1690, sense 7 in 1812.
1.
a. The production of offspring; the action or practice of causing a people, race, etc., to continue in being by procreation; reproduction; (also) the action of causing a plant, animal, etc., to produce offspring or multiply by natural processes. Also figurative.
