frequent是什么意思_frequent怎么读_中英文释义(含例句用法)

frequent: frequent: [16] Frequent comes from Latin frequēns, which meant ‘crowded’ as well as ‘regularly repeated’ (it is not known what the origins of frequēns were, although it may be related to Latin farcīre ‘stuff’, source of English farce). The sense ‘crowded’ was carried over into English along with ‘regularly repeated’, but it had virtually died out by the end of the 18th century. The verb frequent [15] goes back to Latin frequentāre ‘visit frequently or regularly’.
frequent (adj.): mid-15c., "ample, profuse," from Old French frequent, or directly from Latin frequentem (nominative frequens) "often, regular, repeated; in great numbers, crowded, numerous, filled, full, populous," which is of uncertain origin. Watkins says probably from PIE *bhrekw- "to cram together," and compares Greek phrassein "to fence in," Latin farcire "to cram." Meaning "common, usual" is from 1530s; that of "happening at short intervals, often recurring" is from c. 1600.
frequent (v.): late 15c., "visit or associate with," from Old French frequenter "attend frequently; assemble, gather together," from Latin frequentare "visit regularly; do frequently, repeat; assemble in throngs," from frequentem (see frequent (adj.)). Meaning "visit often" is from 1550s. Related: Frequented; frequenter; frequenting.
