See also: Welsh
Sometimes suggested to derive from disparaging stereotypes of the Welsh (“people from Wales”), though firm evidence of this derivation is lacking. Compare gyp (“swindle”) (probably from gypsy (“Roma”)), and jew (“defraud”), from Jew.
- The use of this term is sometimes considered offensive, especially by Welsh people, because it is taken as a negative stereotype of the Welsh.
- The American Heritage Guide to Contemporary Usage and Style (2005, ISBN 0618604995): "Etymologists can find no firm evidence that the verb welsh, meaning "to swindle a person by not paying a debt" or "to fail to fulfill an obligation," is derived from Welsh, the people of Wales."
