mull

Sometimes the best thing to do isn't to act right away, but to mull it over. To mull something is to sit with a thought and turn it around in your mind for a while. You might mull over a hard decision, a new idea, or something that happened earlier in the day. It's more than a quick thought. It usually suggests careful, quiet thinking that takes time. A chef might mull over a new recipe, or a detective might mull over the clues in a case. The word can also remind people of mulled wine, where flavors slowly mix together, and that image fits the feeling of letting an idea develop slowly in your mind.

To mull something means to think about it deeply and carefully, often for some time. It is more than a passing thought. The word suggests a slow, deliberate process in which you go over different sides of an idea, problem, or decision before coming to a conclusion. For example, someone might mull over a job offer for days before accepting it, or mull over a mistake long after the moment has passed.

It is commonly used with over: people mull over plans, choices, questions, or memories. In many cases, the word carries a sense of uncertainty. You have not decided yet, so you keep turning the matter around in your mind. "The committee will need time to mull over the proposed changes" suggests careful thought before any decision is made.

There is also a separate use of mull in cooking and drinks, especially in phrases like mulled wine, where spices are warmed into the drink. That sense is different, but it may help you remember the image of something developing slowly. In everyday English, though, when people say they need to mull something over, they usually mean they need more time to think it through before they act.
