Webster's 1828 Dictionary

KNOW, v.t. no. pret. knew; pp. known. [L. nosco, cognosco, Gr. although much varied in orthography. Nosco makes novi, which, with g or c prefixed, gnovi or cnovi, would coincide with know, knew. So L. cresco, crevi, coincides with grow, grew. The radical sense of knowing is generally to take, receive, or hold.]
