英语 未婚老年女性怎么说

A single, older woman in English can be referred to as an "unmarried older woman," or "a single woman in her later years." Alternatively, you can simply say "a single woman" or "an unmarried woman," without specifying her age. It is also common to use the term "spinster," although this term is somewhat dated and may not be perceived as politically correct by some people.
It is important to be respectful and considerate when referring to someone, regardless of their marital status or age. It is always a good idea to use language that is sensitive and non-judgmental.
