1630s, from explicit + -ly (2). Opposed to implicitly.
adj.

c.1600, from French explicite, from Latin explicitus “unobstructed,” variant past participle of explicare “unfold, unravel, explain,” from ex- “out” (see ex-) + plicare “to fold” (see ply (v.1)).

“Explicitus” was written at the end of medieval books, originally short for explicitus est liber “the book is unrolled.” As a euphemism for “pornographic” it dates from 1971.
