stub n.
Old English stybb "stump of a tree," from Proto-Germanic *stubjaz (source also of Middle Dutch stubbe, Old Norse stubbr), from PIE root *(s)teu- (1) "to push, stick, knock, beat" (see steep (adj.)). Extended 14c. to other short, thick, protruding things. Meaning "remaining part of something partially consumed" is from 1520s.
-y 2
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.
