Also used by single women who find the term "spinster" too old-fashioned and "prude" inapplicable.
It will be a long time before the word "bachelorette" gains the acceptance enjoyed by the word "bachelor".
The term was coined to feminize the masculine word bachelor through the added 'ette' - a wholly idiotic and nonsensical endeavor akin to calling a single mother a fatherette.
This term was born of ignorance and misguided feminist intentions.
Speakers should instead stick to the traditional terms Hen or Doe.
