Apposite \AP-uh-zit\ , adjective;
1. Being of striking appropriateness and relevance; very applicable; apt
This word dates to the 1620's and comes from Latin appositus, which is literally "contiguous, neighboring" but figuratively "fit, proper, suitable." It is the past participle of apponere ("apply to, put near"), which is a compound of ad- + ponere ("near" + "to place"). Ponere is also the forebear of position.
