naeve (n.)

"spot or blemish on the skin," 1610s, from Latin naevus "mole, birthmark, wart," from *gnaevus "birthmark," literally "born in," from PIE root *gene- "to give birth, beget," with derivatives referring to aspects and results of procreation. Now obsolete; the Latin form has been used since c. 1835 in anatomy and zoology.
