Likely a variant of Annette, from Hebrew Hannah, meaning grace or favor.
Annitte is likely a variant of Annette, and behind that family of forms stands the Hebrew name Hannah, meaning grace or favor. The name carries the long history of Anna-related names filtered through French and English usage, so it feels both devotional and gently domestic, with a softness that has kept it usable across generations.
What gives Annitte its particular interest is the slight shift in spelling, which makes a familiar name feel more individualized. It remains close enough to Annette to preserve its graceful associations, but the final -itte creates a lighter, more tailored effect. That kind of variation often appeals to parents who want something traditional in spirit yet uncommon in appearance. Annitte therefore feels like a delicate elaboration rather than a radical reinvention.
