Latin explōrāre : ex-, ex- + perhaps plōrāre, to cry out, as to rouse game.
(American Heritage® Dictionary of the English Language, Fourth Edition)
Recorded since c.1450 (implied in explorator), from Latin explorare "investigate, search out", itself said to be originally a hunters' term meaning "set up a loud cry," from ex- "out" + plorare "to cry", but the second element is also explained as "to make to flow" (from pluere "to flow") (Wiktionary)
