What does mulling mean?
Mulling means thinking about something carefully, usually without reaching an immediate decision. The word is especially familiar from the expression “mull over,” as in “mull over an offer,” and it conveys a process of turning an idea or problem around in the mind. It is commonly used in conversation and informal writing, but it is also perfectly natural in professional contexts when a decision requires reflection. Mulling can apply to practical questions, such as a job offer or a change in plans, and to more personal matters, such as a conversation or future decision. Unlike simply “thinking,” mulling often suggests deliberation, uncertainty, or a willingness to consider several possibilities. It is therefore useful when describing a thoughtful pause before action rather than a quick response.
