'rough'(Modern English )
Old Norse, cp. the OIcel n. kampr 'beard, moustache' (apparently < a PGmc stem without a suffix causing i-mutation, cp. OFris canep) evidently lies behind a rare English adj. (and sb. forms that develop from it): ME camp (OED n.4) and campe (attested only here), next to kemp (OED n.2, MED s.v. kempe (adj.)), first attested in the late 14c. Spellings indicating i-mutation may suggest separate derivation from the native OE by-form (or input from it) for those forms (< PGmc *kanipaz, cp. OE cenep, OFris kenep).

Phonological and morphological markers
This is the unique instance of an adj. <campe>; MED cites a single instance of an adj. <kempe> (see etymological discussion) used by Chaucer to describe coarse shaggy hair (Anderson 1695n and McGee 399 repeat the comparison made by Emerson (1919: 518-19), observing that the same collocation with hores occurs) and then in two other instances with more specific reference to eels.
