1610s, from Latin garrulus "talkative, chattering," from garrire "to chatter," from PIE root *gar- "to call, cry," of imitative origin (compare Greek gerys "voice, sound," Ossetic zar "song," Welsh garm, Old Irish gairm "noise, cry"). Related: Garrulously; garrulousness.

also carefree, "free from cares," 1795, from care (n.) + free (adj.). In Old English and Middle English this idea was expressed by careless.

Old English cearful "mournful, sad," also "full of care or woe; anxious; full of concern" (for someone or something), thus "applying attention, painstaking, circumspect" (late Old English), the main modern sense; from care (n.) + -ful. In Middle English also "miserable, unfortunate," of persons or things; "causing fear, frightening, terrible." Careful-bed (early 14c.) was "sick-bed;" careful-day (c. 1200) was "judgment day."

also care-giver, "one who looks after the physical needs at home of the sick, aged, disabled, etc.," by 1974, from care (n.) + giver. It has, in many senses, the same meaning as caretaker, which ought to be its antonym.

Old English carleas "free from anxiety; unconcerned," from care (n.) + -less; a compound probably from Proto-Germanic (compare Old Norse kærulauss "quit, free").

The meaning "done or said without care, unconsidered" is from 1650s.
