Know - no
From Hull AWE
- The verb 'to know' means 'to have knowledge'. (The mnemonic that the k- is next in the alphabet to the l- of 'to learn' may help some.) 'To know' is an irregular verb whose forms are given at know.
- No may be a noun, and adjective, an adverb or an interjection. In all of these word classes, its meaning is purely negative.
