submissive (adj.)

late 14c., "act of referring to a third party for judgment or decision," from Old French submission or directly from Latin submissionem (nominative submissio) "a lowering, letting down; sinking," noun of action from past participle stem of submittere "to let down, put down, lower, reduce, yield" (see submit).

Sense of "humble obedience" is first recorded mid-15c. Modern French submission has been replaced by doublet soumission. English in 16c.-17c. also had an adjective submiss "humble, submissive." Submissionist in various political historical contexts is from 1828.

word-forming element making adjectives from verbs, meaning "pertaining to, tending to; doing, serving to do," in some cases from Old French -if, but usually directly from Latin adjectival suffix -ivus (source also of Italian and Spanish -ivo). In some words borrowed from French at an early date it has been reduced to -y (as in hasty, tardy).
