Isaac

Traditionally linked to the idea of “he laughs” or “he will laugh.”

Isaac is a classic masculine given name with Hebrew roots and strong international recognition. In Biblical tradition, Isaac is a major patriarchal figure, and that cultural-religious history is a big reason the name appears across many languages and communities today. Etymologically, Isaac is the common English form of the Hebrew name Yitzhak. It’s traditionally linked to a meaning along the lines of “he laughs” or “he will laugh,” though exact grammatical readings can vary by scholarly treatment and transliteration choices. In English, pronunciation is often EYE-zik (two syllables). In other languages you may hear closer-to-the-source pronunciations, and you’ll also see the spelling Isaak in some contexts; if consistency matters, it’s worth choosing the preferred spelling up front.

Etymology: From the Hebrew name Yitzhak (often rendered Isaac in English). In Biblical tradition, Isaac is a major patriarchal figure, which helped spread the name widely.
