Almost always used with the preposition 'to' followed by the trigger (food, animal, drug, plant). Subject is usually a person or animal — distinguish from sense 2, where the subject is the reaction or condition itself.

常見錯誤

❌I am allergic with milk.
✅I am allergic to milk.
💡the fixed preposition is 'to', not 'with' or 'from'.
❌She has allergic to dust.
✅She is allergic to dust.
💡'allergic' is an adjective, so use 'be', not 'have'.

allergic + body symptom noun

同義詞

    much stronger and life-threatening; only for the most severe reactions

文法句型

allergic + medical noun

用法筆記

Only sense that sits directly before a noun (attributive only). The noun describes the symptom or condition (reaction, rash, asthma, shock), not the person. Distinguish from sense 1, where the person is allergic and the structure uses 'be allergic to'.

常見錯誤

❌The cream made my skin allergic.
✅The cream caused an allergic reaction on my skin.
💡the symptom is allergic, not the body part itself.

be allergic to + -ing form

同義詞
  • averse

    more formal; often appears with 'risk' in business writing

  • opposed

    stronger and more public; used about views and policies, not personal habits

反義詞
  • fond of

    opposite informal feeling: liking something rather than avoiding it

文法句型

be allergic to + noun / -ing

用法筆記

Informal and usually humorous — never used in serious medical or formal writing. Frequently followed by an -ing verb naming the disliked activity. Distinguish from sense 1 by context: a real medical trigger (peanuts, dust) signals sense 1, while an activity or abstract noun (housework, hard work) signals sense 3.

常見錯誤

❌He is allergic about hard work.
✅He is allergic to hard work.
💡keep the preposition 'to', the same as sense 1.
