Morphology

immediate + allergy

The meaning 'an allergic reaction that occurs within minutes' is directly and transparently derived from combining 'immediate' (occurring at once) with 'allergy' (an adverse bodily reaction). This simple adjective + noun composition follows standard English patterns and is cross-linguistically straightforward, so a B1 learner who knows both words would readily infer the MWE meaning.

Etymology

Immediate allergy combines immediate (meaning 'right away') and allergy (a strong reaction by the body). Imagine someone eats a peanut and, within minutes, their skin breaks out in hives or their throat swells—this sudden, fast reaction is the memory hook, so it means 'an allergic reaction that happens within minutes'.
