Cacy

Cacy has a subtle nickname feel but still stands firmly as a given name. It’s of Irish origin and means “brave,” “vigilant,” and “watchful.” Considered a variant of the popular moniker Casey, it might also be a shortened form of Acacia, which would add the possible meaning “thorny” to its collection. When baby Cacy arrives and begins to explore the world around them, their name will remind them to be courageous and think before they act.
