couple

couple: [13] The notion underlying couple is of ‘joining’. The noun came into English via Old French from Latin cōpula ‘tie, connection’. This was a compound noun formed from the prefix com- ‘together’ and the verb apere ‘fasten’ (source of English apt, adapt, adept, and inept). Derived from it was the verb cōpulāre, source of English copulate [17].
=> adapt, adept, apt, copulate, inept
