recognize

recognize: [15] Latin gnōscere ‘become acquainted’ came from the same prehistoric Indo-European base, *gnō-, as produced English know. Combination with the prefix co- ‘with’ gave cognōscere ‘know’ (source of English cognition, quaint, etc). And this in turn had the prefix re- ‘again’ added to it to produce recognōscere ‘know again’, which found its way into English via reconniss-, the stem of Old French reconnaistre (the -ize ending is an English introduction).

English has three noun derivatives of the verb: recognition [15], from Latin recognitiō; recognizance [14], now purely a legal term, borrowed from Old French reconnissance and remodelled on the basis of recognize; and reconnaissance [19], borrowed from modern French during the Napoleonic wars. Reconnoitre [18] comes from the now obsolete French reconnoître, which like its surviving variant reconnaître goes back to Latin recognōscere.
