Question

How do you make the last name Perez plural? Does the rule for "s" also apply to "z"?

Answer 1

Perezes

Explanation:

Last names ending in ch, sh, s, x, and z add -es to the end of the word to form the plural.
Sometimes -zes needs to be added to the end of a word (not a last name) ending in -z to make it plural. Sometimes -es is added.

Examples:

Fez (pl. fezzes, fez ends in z, add -zes to make it plural)

Waltz (pl. waltzes, waltz ends in z, add -es to make it plural)
