late 14c., blober "a bubble, bubbling water; foaming waves," probably echoic of bubbling water. Original notion of "bubbling, foaming" survives in the figurative verbal meaning "to weep, cry" (c. 1400). Meaning "whale fat" first attested 1660s; earlier it was used in reference to jellyfish (c. 1600) and of whale oil (mid-15c.). Compare bubble.
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).
