Question

If spinster is a single woman then what is maiden?

Answer 1

Spinster originally meant "a spinner of thread," and as that was a job typically done by unmarried women, it came to have the meaning — even in legal documents — of "single woman." Another term for spinster is the equally old-fashioned sounding old maid. Either way, it means a woman who never got married.

Answer 2

spinster and maiden both are called unmarried woman . they are synonyms.
