Morphology

allergic + reaction

The meaning is directly compositional: 'allergic' (having hypersensitivity to a substance) combined with 'reaction' (a bodily/physiological response) yields the notion of a bodily response caused by an allergy. This is a common, cross-linguistically similar medical collocation, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Allergic reaction comes from the image of your body suddenly treating a harmless thing as dangerous: allergic means related to an allergy and reaction is the body's strong response. So, when your body 'overreacts' to something like pollen or peanuts, you get symptoms such as swelling, sneezing, or difficulty breathing.
