Hence the OE knaeve {n’aIvÊve} From Old French —-> Latin naevus to connect, constrict, or be grossly becutten Later borrowed from Finnish naïve meaning to be beholden to the connection thereof, hence leading.
Earliest usage in English, from Sir Thomas Tomlison’s Practical Guide For The Gifted Sub Hunter, circa October 1593, “and thine whence betroth, a single nave from fetal navel, doth give thine crimson hunt.”
