Surface Forms

fever blister singular

Morphology

fever + blister

The noun combines 'fever' (high body temperature/illness) and 'blister' (a raised, fluid-filled bubble), so a B1 learner who knows both words can infer it denotes a blister associated with illness—typically the small sore on the lip. Although it is a specific medical term for a cold sore (HSV-1), the meaning is directly compositional and predictable from its parts.

Etymology

Fever blister is named after the simple picture of a small blister that often appears when someone has a fever or feels sick. That's why it now means a small, painful blister on the lip or face caused by a virus.
