Definition
Meaning
To cool or chill something, especially food or drink, to a low temperature in order to preserve it.
To subject something to a cooling process, often using a mechanical device (refrigerator), to slow down chemical or biological processes like bacterial growth or spoilage. In broader technical contexts, it can refer to any process of lowering temperature systematically.
Linguistics
Semantic Notes
The verb is often used in the imperative mood for instructions (e.g., on food packaging). It implies a deliberate, controlled process of cooling for preservation, distinct from simply 'cooling' which can be passive. It is a causative verb (to cause something to become cold).
