Winter

Winter is also used as a masculine given name in English. However, it's more common for females. So, I think that the "Gender" of this name should be updated from "Feminine" to "Feminine & Masculine".

Meaning: From the English word for the season set between December and March, which is derived from the Old English Winter or the Old High German wintar. This was a nickname for a person with a cold personality. It is also the Old Danish form of Vetr which also means 'Winter'.

Also used as a German, Danish, and Swedish surname. Too bad it's never used in these languages as a given name.
