Zaccai

Zaccai comes from the Hebrew name Zakkai, traditionally meaning pure. The name appears in biblical lists of families returning from exile, giving it a specific Old Testament setting beyond its short, modern-looking shape. Its double c reflects one established way of writing the Hebrew name in English.

Zakkai makes the consonant sound more visible, while Zaccai follows the familiar biblical spelling. Zac is a possible short form, although the name itself is already concise. For a family considering a less familiar biblical choice, the return-from-exile reference provides a story to explore, and the purity meaning offers a clear starting point without needing to borrow the meaning of similar names such as Zachary.
