1610s, "done with care," from Latin accuratus "prepared with care, exact, elaborate," past participle of accurare "take care of," from ad "to" (see ad-) + curare "take care of" (see cure (n.1)). The notion of doing something carefully led to that of being precise (1650s). A stronger word than correct (adj.), weaker than exact (adj.). Related: Accurately; accurateness.
