febrile - feverish
The word ‘febrile’ can be used in a literal and figurative sense. Literally, it is used in a medical context to describe symptoms or behaviour marked or caused by fever. In a figurative and more commonly used sense, it expresses a state of great excitement, activity, or energy. In the latter context, it can have both positive and negative connotations. ‘Febrile’ is pronounced ‘feh-brile' not ‘fee-brile’ as many assume.
