英文词源
add
add: [14] Etymologically, add means simply ‘put to’. Its source is Latin addere, a compound verb formed from the prefix ad- ‘to’ and the stem -dere ‘put’ (which is related to English do). Its original meaning in English was simply ‘join one thing to another’; its specific mathematical use did not develop until the early 16th century.
=> do
add (v.)
late 14c., "to join or unite (something to something else)," from Latin addere "add to, join, attach, place upon," from ad- "to" (see ad-) + -dere comb. form meaning "to put, place," from dare "to give" (see date (n.1)). Meaning "to do sums, do addition" also is from late 14c. Related: Added; adding. To add up "make sense" is from 1942.
