v.

“to crack,” mid-15c., chappen (intransitive) “to split, burst open;” “cause to crack” (transitive); perhaps a variant of choppen (see chop (v.), and cf. strap/strop), or related to Middle Dutch kappen “to chop, cut,” Danish kappe, Swedish kappa “to cut.” Related: Chapped; chapping. The noun meaning “fissure in the skin” is from late 14c.

[1700s+; fr a shortening of chapman, ”peddler; peddler’s customer,” hence analogous with customer in the same sense]
