meaning of howdy
Howdy is an informal greeting, commonly thought to have originated as a shortened form of the greeting How do you do?. It was first recorded as part of the South England dialect in 1680.[1] Literature from that period includes the use of How-do, how-do and How as a greeting used by the Scottish when addressing Anglo settlers in greeting. The double form of the idiom is still found in parts of the American Southwest as Howdy, howdy.
