Knit
Old English cnyttan, of West Germanic origin; related to German dialect knütten, also to knot1. The original sense was ‘tie in or with a knot’, hence ‘join, unite’ (knit (sense 2 of the verb)); an obsolete Middle English sense ‘knot string to make a net’ gave rise to knit (sense 1 of the verb).
