stumpy (adj.)

"part of a tree trunk left in the ground after felling," mid-15c. (implied from late 13c. in surnames); from mid-14c. as "remaining part of a severed arm or leg;" from or cognate with Middle Low German stump (from adjective meaning "mutilated, blunt, dull"), Middle Dutch stomp "stump," from Proto-Germanic *stamp- (source also of Old Norse stumpr, Old High German stumph, German stumpf "stump," German Stummel "piece cut off"), from PIE *stebh- "post, stem; to support" (see step (v.).

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.
