Origin: Middle English expoune (in the sense ‘explain (what is difficult)’): from Old French espon-, present tense stem of espondre, from Latin exponere ‘expose, publish, explain’, from ex- ‘out’ + ponere ‘put’. The origin of the final -d (recorded from the Middle English period) is uncertain (compare with compound, propound).
