'to speak, say, converse'(Modern English carp)
cp. OIcel karpa ‘to brag, boast’. The ulterior etymology of this word is obscure. The difference in sense between the ME and ON may be the result of bleaching (although it has also been suggested that more specific sense is a later Scandinavian development: see MED), and the possiblility of influence from Lat capere 'to pluck, gather', fig. 'to carp at, villify' cannot be ruled out, but seems unlikely (see further OED and DMLBS s.v.).
