jalapeno

The word 'jalapeño' is a direct borrowing from Mexican Spanish, where 'jalapeño' literally means "from Jalapa." Jalapa (formally Xalapa) is the capital city of the Mexican state of Veracruz, a region historically known for cultivating this specific variety of chili pepper. The Spanish suffix '-eño' (from Latin '-ēneus', meaning "of or pertaining to") is commonly used to form adjectives denoting origin, similar to '-an' in English (e.g., 'Mexican'). Thus, the term originated as a geographical descriptor for the pepper cultivated in that area. As the pepper gained international popularity, primarily through Mexican cuisine, the Spanish word was adopted wholesale into English, retaining its original reference to its place of origin while now primarily signifying the pepper's distinct culinary characteristics.

This word is a loanword from Mexican Spanish, adopted as a single lexical unit. It is a toponym derived from the place name 'Jalapa' (or Xalapa) in Veracruz, Mexico, with the Spanish suffix '-eño' indicating origin or association.
