enumerate (v.)

1640s, from or modeled on Latin enumeratus, past participle of enumerare "to reckon up, count over, enumerate," from assimilated form of ex "out, out of" (see ex-) + numerare "to count, number," from numerus "number" (see number (n.)). Middle English had annumerate (early 15c.). Related: Enumerated; enumerating.
