Translation

allergy

Word origin

Coined in 1906 by the Viennese paediatrician Clemens von Pirquet from Greek allos, other, and ergon, work or reaction: the body reacting in an altered way. It reached Esperanto as an already international medical term.

Origin
Greek
Root
allos + ergon
English cognates
allergy, allegory, energy

Examples

.

I have an allergy to milk.

.

His allergy appears every spring.

.

The skin went red because of the allergy.

The tempting parse is - plus ergio, and it is a mirage in both halves. Yes, al is a live Esperanto preposition, and yes, you do say . But the - in this word is Greek allos, other, with one of its two Ls worn off, and there is no Esperanto root ergi- at all. Strip nothing. - is one piece.

The genuine sibling is next door and does have a real Greek seam: energio is plus ergon, work inside a thing. The -ergi- you can half-see in both words is the Greek ergon, which also gave English erg, surgery and organ. That is a shared history, not an Esperanto affix, and it does not license you to build new words with it.

The everyday vocabulary around it: alergia for allergic, o for the person who has one, and the preposition is . alergia poleno is how you say it at the table, and a is a food allergy.
