Etymology

It is borrowed from Latin opponens (“setting against”), the present participle of oppōnere (“to set against, oppose”),[2][3][4] from ob (“against, in front of”) and pōnere (“to put, place”) (see position).[3][2]

Earliest recorded meaning

The general sense, one who opposes another in a contest or fight, is from 1615.[5][3] The adjective, opposing, is from 1647,[2][5] and in anatomy it describes a muscle that moves the thumb against the fingers (1842).[5]
