hasp (n.) Look up hasp at Dictionary.com
Old English hæpse "fastening, clip," with later Old English metathesis of -p- and -s-. Related to Old Norse hespa "hasp, fastening," Middle Dutch, German haspe "clamp, hinge, hook," but all are of uncertain origin. The meaning "a quantity of yarn" is from c. 1400 but perhaps not the same word.
