Etimoloji
From the now dated noun Knips (“flip; dab”), itself derived with the northern suffix -s from the verb Middle Low German knippen (“to flip; to slap; to wink”). Compare Dutch knippen. This verb may plausibly be thought to be derived from Middle Low German knīpen (“to squeeze”) (see kneifen), but onomatopoeia has certainly played a role in the development of this root.
