Old-womanishness refers to a characteristic or behaviour that is typically associated with elderly women, such as being cautious, frugal, or conservative. Synonyms for this term include granny-esque, matronly, matriarchal, old-fashioned, and dowdy. Another phrase that can be used to describe this type of behavior is "old-school," which suggests a strict adherence to traditional values and ways of doing things. In contrast, antonyms for old-womanishness might include youthful, modern, trendy, or progressive. It's important to note that these terms should be used with care and sensitivity, as they can reinforce ageist stereotypes and stigmatize older women.
