The only free and comprehensive online etymological dictionary of the Spanish language
ah (Interjection) Denotes surprise or pain akin to English ah!
First attested in the 15th cent. From Latin ah 'id.' Onomatopoetic. Perhaps continued from Proto-Italic *ā 'id.' From Proto-Indo-European *eh2 'id.'
Also used to mark a question. For example, ¿pero no fuiste a Peru, ah? "but you didn't go to Peru, eh?" Common across all Romance languages and regional dialects.

As a common but simple interjection, the word is relatively unstudied. Its simplistic phonology makes it resistent to etymological analysis, as it could conceivably arise ex nihilo.

A series of shadow updates were implemented over the past month: changes in formatting and font, an improved layout to display cognates in other languages, and information added.
