mid-14c. (trans.), late 14c. (intrans.), from O.Fr. varier, from L. variare "change, alter, make different," from varius "varied, different, spotted;" perhaps related to varus "bent, crooked, knock-kneed," and varix "varicose vein," from a PIE base *wer- "high raised spot or other bodily infirmity" (cf. O.E. wearte "wart," Swed. varbulde "pus swelling," L. verruca "wart").
