Selected source glosses provide context, not a complete modern definition inventory

The verb is derived from Late Middle English knappen (“to strike (something)”); further etymology uncertain, probably related to Middle Dutch knappen, cnappen (“to break (something) with a sharp sound, snap; to crack or crackle”) (modern Dutch knappen), probably ultimately onomatopoeic. The noun is derived from Late Middle English knap, knappe (“sharp blow, strike”); further etymology uncertain, possibly from the verb (see above), or related to an ancestor of Danish knep and Swedish knäpp (“a flick, rap, snap”), probably ultimately onomatopoeic.
