Alter

Jewish (Ashkenazic): from the Yiddish personal name Alter, an inflected form of alt ‘old’. This was in part an omen name, expressing the parents’ hope that the child would live a long life; in part an apotropaic name, given to a child born after the death of a sibling, but also said to have sometimes been assumed by someone who was seriously ill. The purpose is supposed to have been to confuse the Angel of Death into thinking that the person was old and so not worth claiming as a victim.
