jowly (adj.)

"fold of flesh under the jaw," 1590s, alteration of Middle English cholle "fold of flesh hanging from the neck or jaw, double chin" (c. 1300), which is perhaps from or related to Old English ceole "throat" (from PIE root *gwele- (3) "to swallow;" see gullet), but the phonetic development would be abnormal. Also see jowl (n.1).

adjective suffix, "full of or characterized by," from Old English -ig, from Proto-Germanic *-iga- (source also of Dutch, Danish, German -ig, Gothic -egs), from PIE -(i)ko-, adjectival suffix, cognate with elements in Greek -ikos, Latin -icus (see -ic). Originally added to nouns in Old English; used from 13c. with verbs, and by 15c. even with other adjectives (for example crispy). Adjectives such as hugy, vasty are artificial words that exist for the sake of poetical metrics.
