Origin & History of “reveal”

To reveal something is etymologically to ‘unveil’ it. The word comes via Old French reveler from Latin revēlāre ‘unveil, disclose’, a compound verb formed from the prefix re- ‘back’ (in the sense ‘reverting to a former condition’) and vēlum ‘veil’ (source of English veil).
