late 14c., used in Rev. ix:11 of “the angel of the bottomless pit,” and by Milton of the pit itself, from Hebrew Abhaddon “destruction,” from abhadh “he perished.” The Greek form was Apollyon.

destruction, the Hebrew name (equivalent to the Greek Apollyon, i.e., destroyer) of “the angel of the bottomless pit” (Rev. 9:11). It is rendered “destruction” in Job 28:22; 31:12; 26:6; Prov. 15:11; 27:20. In the last three of these passages the Revised Version retains the word “Abaddon.” We may regard this word as a personification of the idea of destruction, or as sheol, the realm of the dead.
