The term "old battleaxe" is often used to describe a difficult and formidable woman. However, it is important to recognize that using gendered slurs is not appropriate. Instead, one could use synonyms such as "hard-nosed," "stern," "tough," or "resolute." These words convey a similar meaning without being offensive or derogatory. Another option is to describe the specific behavior or traits that make the person challenging, such as "unyielding," "stubborn," "demanding," or "rigid." By avoiding gendered slurs and using more descriptive language, we can communicate effectively without resorting to hurtful language.
