Surface Forms
Morphology
type + I + allergic + reaction
The phrase is compositionally built from 'type' + 'allergic' + 'reaction', so a learner who knows those words can infer this is a particular class or kind of allergic reaction. However, the specific meaning of 'Type I' (the immediate-onset, IgE-mediated category with features like anaphylaxis) is a technical medical classification not predictable from the surface words alone, making full understanding unlikely without prior exposure.
Etymology
Type I allergic reaction comes from a list doctors made where type I means the 'first' and fastest kind of allergy. Think of it as your body sounding an instant alarm and causing hives or swelling within minutes, so the name points to a quick, 'immediate' reaction.
