What is the feminine noun for a woman going stag to a dance?

Answer 1

The feminine noun for a woman going stag to a dance is a "lone wolf." Just kidding! The term you're looking for is a "lone doe." So if you see a lady hitting the dance floor solo, you can call her a lone doe strutting her stuff!

Answer 2

In English there are no masculine or feminine forms. English uses gender specific nouns for male or female.

The noun stag is a word for a male deer; the noun doe is a word for a female deer.

The term 'going stag' is a slang term for a male attending an occasion alone; there is no equivalent term for a female attending alone. A female attending an occasion alone would be referred to as a woman, a loner, a single, etc.
