scrimmage n.

late 14c., scarmuch, "irregular fight, especially between small numbers of soldiers," from Old French escarmouche "skirmish," from Italian scaramuccia, earlier schermugio. This is held to be probably from a Germanic source, with a diminutive or depreciatory suffix (see -ish), from Proto-Germanic *skirmjanan (compare Middle Dutch schermen "protect," Old High German scirmen "to protect, defend," German Schirm "umbrella," originally "leather protection on a shield"), from PIE root *sker- (1) "to cut."

It was influenced in Middle English by a different verb, skirmysshen, "to brandish a weapon," from Anglo-French eskirmiss-, stem of eskirmir "to fence," from Frankish *skirmjan, from the same Germanic source as the other word. An earlier verb in English was skirm (Middle English skirmen), c. 1200, "to fence, fight with a weapon, fight in small parties," from Anglo-French.

Compare scrimmage, which is a variant of it; for the form, compare rubbish. Other modern Germanic languages augment the diminutive with a second suffix: German scharmützel, Dutch schermutseling, Danish skjærmydsel. Skirmish-line "line of soldiers thrown out in advance of the main part of an army" is attested by 1864.

1888, "a scrimmage in rugby," abbreviation of scrummage, a variant form of scrimmage (n.). The transferred sense of "continued noisy throng" is by 1950.

also *ker-, Proto-Indo-European root meaning "to cut."
