promise

promise: [14] Latin prōmittere originally meant simply ‘send forth’ (it was a compound verb formed from the prefix prō- ‘forward’ and mittere ‘send’, source of English mission, missile, transmit, etc). But it soon evolved metaphorically via ‘say in advance, foretell’ to ‘cause to expect’ and hence ‘promise’ – the sense adopted into English via its past participle prōmissum.
=> admit, commit, missile, mission, submit, transmit

promise (n.)

c. 1400, "a pledge, vow," from Old French promesse "promise, guarantee, assurance" (13c.) and directly from Latin promissum "a promise," noun use of neuter past participle of promittere "send forth; let go; foretell; assure beforehand, promise," from pro- "before" (see pro-) + mittere "to put, send" (see mission). The ground sense is "declaration made about the future, about some act to be done or not done."

promise (v.)

c. 1400, from promise (n.). Related: Promised; promising. Promised land (1530s) is a reference to the land of Canaan promised to Abraham and his progeny (Hebrew xi:9, etc.; Greek ten ges tes epangelias).
