Frequently Asked Questions
It is primarily a surname (a patronymic meaning 'son of Isaac'), though it can very rarely be used as a given name.
Typically /ˈaɪ.zəks/. The final 's' is pronounced as /s/, not /z/.
No. The 's' denotes the patronymic 'son of', not possession. The correct form is 'Isaacs'. 'Isaac's' would be the possessive form of the first name Isaac.
As a proper noun referring to a family, it can be used plurally without change (e.g., 'the Isaacs are here'). It is not a countable common noun.
