scraggy (adj.)

1540s, "lean person or animal, a raw-bones;" perhaps from a Scandinavian source (compare Norwegian skragg "a lean person;" dialectal Swedish skraka "a great, dry tree; a long, lean man," skragge "old and torn thing," Danish skrog "hull of a ship; carcass," Icelandic skröggr, a nickname of the fox); perhaps from the same source as shrink.

By 1640s as "lean end of a cut of meat," hence "neck" (18c.) and thence a range of slang verbal terms for "to strangle, to hang; to kill" in 19c.-20c.

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.
