leap

leap: [OE] Prehistoric Germanic *khlaupan was the source of English leap, and of its relatives German laufen and Dutch loopen (these both denote ‘run’, a meaning which leap used to have – and which is preserved in its first cousins lope [15], a borrowing from Old Norse, and elope). It is not known where it ultimately came from, although a connection has been suggested with Indo-European *kloub-, source of Lithuanian ?lubuoti ‘limp’. The verb loaf may be related.
=> loaf, lope

leap (v.)

c. 1200, from Old English hleapan "to jump, run, leap" (class VII strong verb; past tense hleop, past participle hleapen), from Proto-Germanic *hlaupan (cognates: Old Saxon hlopan, Old Norse hlaupa, Old Frisian hlapa, Dutch lopen, Old High German hlouffan, German laufen "to run," Gothic us-hlaupan "to jump up"), of uncertain origin, with no known cognates beyond Germanic. Leap-frog, the children's game, is attested by that name from 1590s; figurative use by 1704.

First loke and aftirward lepe [proverb recorded from mid-15c.]

leap (n.)
