loma

The word 'loma' entered English in the mid-19th century as a direct loanword from American Spanish, used primarily in the southwestern United States and other regions with Spanish colonial history. Its ultimate origin is obscure but is likely from a substrate language of the Iberian Peninsula, predating Latin. The term fills a specific topographic niche in English, describing a landform characteristic of certain arid and semi-arid landscapes. Its journey from a local Spanish term to a specialized English geographical noun exemplifies how language adopts words for concrete, region-specific features.

This word is a direct borrowing from Spanish, where it means "hill" or "low ridge." The Spanish term itself is of uncertain origin, possibly from a pre-Roman Iberian language.
