"to walk with regular tread," early 15c., from Middle French marcher "to march, walk," from Old French marchier "to stride, march," originally "to trample, tread underfoot," perhaps from Frankish *markon or some other Germanic source related to obsolete Middle English march (n.) "borderland" (see march (n.2)). Or possibly from Gallo-Roman *marcare, from Latin marcus "hammer," via notion of "tramping the feet." Meaning "to cause to march" is from 1590s. Related: Marched; marching. Marching band is attested from 1852. Italian marciare, Spanish marchar are said to be from French.
