The feminine of manager is manager. There is no specific feminine form of the word "manager" in the English language. The term applies equally to both men and women.
While some might use "female manager" or "woman manager" to emphasize gender, these are not grammatically correct alternatives. "Manager" itself is gender-neutral.
Here are some examples:
- "The manager of the team is highly skilled."
- "She is a successful manager in the company."
The use of "manager" as a gender-neutral term reflects the increasing recognition of gender equality in the workplace.
