'fever-prone' originates from the English word 'fever' combined with the suffix '-prone,' which indicates a tendency or inclination.

'Fever' comes from the Old English word 'fēfor,' which was derived from the Latin 'febris,' meaning 'fever.' The suffix '-prone' is derived from the Latin 'pronus,' meaning 'inclined' or 'leaning forward.'

Initially, 'fever' referred to a high body temperature due to illness, and 'prone' indicated a tendency. Together, 'fever-prone' has consistently meant having a tendency to develop fevers.
