💡Pro Tip

Avoid confusion with 'intolerant'

'Allergic' implies an immune system response, while 'intolerant' (e.g., lactose intolerant) refers to digestive issues without immune involvement.

⚡Gold Rule

Use 'allergic to' for substances

Always pair 'allergic' with 'to' when referring to allergens (e.g., allergic to cats, allergic to dust).

Medical vs. metaphorical use

In medical contexts, 'allergic' describes physical reactions; in informal speech, it may describe strong dislikes (e.g., 'I'm allergic to bad movies').

📖Word Origin

From French *allergique*, derived from Greek *allos* (other) + *ergon* (work, reaction), coined in 1906 by pediatrician Clemens von Pirquet to describe altered reactivity.

📝Usage Notes

In medical contexts, 'allergic' is typically followed by 'to' (e.g., allergic to pollen). In informal contexts, it may describe strong dislikes (e.g., allergic to exercise). Always clarify context to avoid ambiguity.
