A perfect piece of Nash, Geoff! Thanks!

Then of course, there's also spinster and dowager.

But why do single older women seem to have several nomenclatures when single men of any age are simply relegated to bachelor or confirmed bachelor?
Remember the TV sitcom (US) in the 50's, Bachelor Father, starring John Forsythe, about a single father and his two daughters? It seems that people who never married, or who remained unmarried, especially women, were stigmitized to a degree by society up until the late 20th century...thus words like spinster imply a note of disparagement, such as in the phrase you old spinster. And bachelor was a "polite" way of saying a man was single. I remember these attitudes still being prevalent when I was a young child.
