Definition

To brew or develop, especially of something bad or undesirable.

colloquialweatheremotion

How it's used

Focuses on the slow, internal buildup of something negative, such as bad weather, anger, or a festering wound. It implies a process that happens quietly over time before finally breaking out or becoming visible. It is rarely used for positive developments.

Examples

The sky is pitch black, it looks like it's about to rain.
He is always brooding in his room, why not go out for a walk?

Common phrases

to be about to rain
to brood or sulk

Common mistake

Do not confuse this with the Mandarin word for soaking or steeping, as in 漚茶. In Cantonese, it almost exclusively carries a negative connotation of something brewing or festering.
