contain: [13] Contain comes ultimately from Latin tenēre ‘hold’, source of a wide range of English words from abstain to tenor. In the case of contain the immediate ancestor, via Old French contenir, is Latin continēre ‘hold together, enclose, contain’, a compound formed with the prefix com- ‘together’. Contain still adheres fairly closely to the meaning of its Latin original, but other descendants, such as content, continent, continue, and countenance, have branched out a lot semantically.
