mess

\ \ [13] Mess comes via Old French mes from late Latin missus, a derivative of the verb mittere ‘send’ (source of English admit, mission, transmit, etc). This meant ‘sending, placement’, and its original metaphorical application was to a ‘round or heat of a contest’, but it was also used for a ‘course of a meal’, and this was the sense in which it originally entered English. Traces of the food connection survive in the mess of pottage (literally a ‘dish of porridge or gruel’ made from lentils) for which Esau sold his birthright to Jacob, and in the sense ‘communal eating place’ (as in ‘sergeants’ mess’), which developed in the 16th century. But the main present-day meaning, ‘disorderly thing or condition’, did not emerge until as recently as the 19th century, apparently based on the notion of a mess as a ‘dish of assorted foodstuffs dumped unceremoniously and without thought on to a plate’.
