Noel can also be used as a feminine name. Noel can be used for both males and females, though Noelle is only used for females.Noel doesn’t sound masculine enough to be used only on males because it’s closer to the feminine form Noelle that can’t be used for males at all! Noel used to be exclusively masculine, but now it has the alternative to be feminine. I personally like the name Noel for boys and girls, but I prefer it on a boy because it was mostly made to be masculine. Noel for a girl still sounds elegant and unique. It’s not too boyish or strong. I like the Christmas association.
