c.1300, from O.Fr. escarmouche "skirmish," from It. scaramuccia, probably from a Gmc. source (cf. O.H.G. skirmen "to protect, defend"), influenced in M.E. by a separate verb skirmysshen "to brandish a weapon," from O.Fr. eskirmiss-, stem of eskirmir "to fence," from Frankish *skirmjan, from the same Gmc. source. The verb is attested from c.1470. Cf. also scrimmage.
