That is my daughters name. We pronounce it ZAY-da. She is a feisty yet empathetic child. Very strong-willed. She is also very “lucky” as for the meaning of her name. She was a miracle against all odds... though she was a surprise. I did not know the meaning of her name when she was named, but “lucky” is indeed fitting.
I would pronounce this name as zay-da. It sounds just like the word for "more" which makes sense coming from "to increase." I would use this name for a second daughter, perhaps for a twin when we expected only one baby. ;) I wonder if this name will get more popular thanks to all the "ay" sounds we hear lately (Aiden, Jayden, etc.).
Although this is a beautiful name, it is a bit harsh and odd. It reminds me of black people (probably because of how it sounds close to Jada and Daija) and dogs. (My grandma, for years, had a big, vicious dog by the name of Zaida.
