The word "nab" is believed to have originated from the Middle English word "nabben" or "knabben", which meant "to snatch or seize". It is derived from the Scandinavian word "gnabb", meaning "to snatch or steal". This ultimately traces back to the Old Norse word "gnúa", which has the same meaning. The term "nab" has been used in English since the 15th century and has retained its sense of quickly grabbing or catching something ever since.
