interval的词源

英文词源

interval: interval: [13] The val- of interval represents Latin vallum ‘rampart’ (source of English wall) – so etymologically the word means ‘space between ramparts’. That was the original sense of its Latin ancestor, intervallum, but already in the classical period the metaphorical ‘gap in time, pause’ was developing.
=> wall
interval (n.): early 14c., from Old French intervalle (14c.), earlier entreval (13c.), from Late Latin intervallum "space, interval, distance," originally "space between palisades or ramparts," from inter "between" (see inter-) + vallum "rampart" (see wall (n.)). Metaphoric sense of "gap in time" was present in Latin.

inter-,在内，在中间，相互，-val,墙，词源同wall.原指两堵墙之间的空间，后引申词义间隔，间歇。
