Family name origins & meanings
- Italian and Spanish : nickname for someone with close-cropped hair, from raso ‘level’, ‘smooth’, ‘bare’; alternatively, the Italian name may correspond to the past participle rasato, meaning ‘shaven’. Raso also means ‘satin’, and in some cases the name may have arisen from this sense of the word.
- Portuguese, Galician and Spanish : habitational name from any of the places called Raso, in Portugal, and in A Coruña (Galicia) and Ávila provinces.
