Origin: 1325–75; (v.) Middle Englishrevelen < Middle Frenchreveler < Latinrevēlāre to unveil (see re-, veil); (in defs 4 and 5) derivative of obsolete revale to lower < Old Frenchrevaler (re-re- + (a)valer to lower, verbal derivative of the phrase à val down; see vale)
Synonyms 1, 2. unveil, publish, impart, tell, announce, proclaim. Reveal, disclose, divulge share the meaning of making known something previously concealed or secret. To reveal is to uncover as if by drawing away a veil: The fog lifted and revealed the harbor. To disclose is to lay open and thereby invite inspection: to disclose the plans of an organization. To divulge is to communicate, sometimes to a large number of people, what was at first intended to be private, confidential, or secret: to divulge the terms of a contract.
late 14c., from O.Fr. reveler (14c.), from L. revelare "reveal, uncover, disclose," lit. "unveil," from re- "opposite of" + velare "to cover, veil," from velum "a veil" (see veil). Revealed religion, as opposed to natural religion, is attested from 1719.
