Note: The standard English pronunciation of devil with the outcome of a short vowel presumably reflects shortening of the Old English dipththong -ēo-/-īo- in syncopated forms, as the nominative plural dēoflas. The early Modern English form divel (as in Shakespeare), preserved in regional and dialectal speech in both Britain and the U.S., shows Middle English shortening of original ẹ̄ to i. Forms such as Middle English dele and early Scots dele show loss of v before a syllable ending in a liquid. — Greek bállein and its many prefixed forms are rich in nominal derivatives, usually with o-grade (as in diábolos, perhaps secondarily agentive, after the adjective diábolos "slanderous, backbiting") or with zero grade blē- (going back to *g^wl̥h₁-C-). That the original consonant was a labiovelar is assured by the Arcadian form esdellō, with e-grade, corresponding to Greek ekballō "expel, let fall." Despite its thoroughly Indo-European formal properties, bállein has no certain cognates outside Greek.
