Morphology

be + allergic + to

The meaning is compositionally predictable: 'be' + the adjective 'allergic' with the preposition 'to' simply indicates having a hypersensitive reaction to something, so a B1 learner who knows 'allergic' and the function of 'to' can derive the meaning. The construction is cross-linguistically common (e.g. Spanish 'ser alérgico a'), reinforcing its transparency for learners.

Etymology

Be allergic to comes from the image of the body as a guard that is too active and attacks harmless things like pollen, cats, or shellfish. So saying someone is allergic to something means they 'react badly' or 'suffer' when they touch or eat it.
