allergy

== English == === Etymology === Borrowed from German Allergie. Coined by Austrian pediatrician Clemens von Pirquet in 1906 from Ancient Greek ἄλλος (állos, “other”) + ἔργον (érgon, “work, activity”), on the model of Energie. === Pronunciation === enPR: ălʹər-jē; IPA(key): /ˈæl.əɹ.d͡ʒi/ (UK) IPA(key): [ˈæl.ə.dʒi] (US) IPA(key): [ˈæl.ɚ.d͡ʒi] (Indic) IPA(key): /əˈlɜ(ɾ)dʒi/ Hyphenation: al‧ler‧gy === Noun === allergy (plural allergies) (medicine, immunology, loosely) A disorder of the immune system causing adverse reactions to substances (allergens) not harmful to most and marked by the body's production of histamines and associated with atopy, anaphylaxis, and asthma; any condition of hypersensitivity to a substance. (medicine, immunology, strictly) Specifically, hypersensitivity of class I in the modern classification thereof: the immunoglobulin E–mediated type. (informal, figuratively) An antipathy, as toward a person or activity. ==== Usage notes ==== From its coining in 1906 until the 1960s, the word allergy always covered any kind of hypersensitivity reactions. Since then, the word also has a stricter sense referring specifically to only a subset of them, mediated by a certain antibody. Both senses remain in wide use. ==== Synonyms ==== (disorder of the immune system): type 1 hypersensitivity (hypersensitivity): intolerance ==== Hypernyms ==== (disorder of the immune system): hypersensitivity ==== Derived terms ==== ==== Descendants ==== → Bengali: এলার্জি (elarji) → Cebuano: alerdyi → Hindi: एलर्जी (elarjī) → Urdu: الرجی (alarjī) → Tamil: அலர்ஜி (alarji) ==== Translations ==== === See also === allergy on Wikipedia.Wikipedia Hypersensitivity on Wikipedia.Wikipedia === Anagrams === Gallery, largely, regally, Allgyer, gallery
