Zack (personal name)

Zack (and variant spellings Zach, Zac, Zak, Zakk) is a male personal name (or, depending on which definition of "personal name" one uses, part of a personal name). It is sometimes a given name (or "first name"), but more often it is hypocorism (affectionate variation of a personal name) which takes the place of a given name, usually Zachary.
