Spanish; Portuguese (Brás): from a vernacular form of the personal name Blasius popularized through the cult of the 4th-century Christian martyr. Compare Portuguese Braz . French: from Old French bras ‘arm’ a term used as a measure of length hence a metonymic occupational name for a surveyor. Breton (mainly Le Bras): nickname for a corpulent man from bras ‘big’.
