The word "blowoff" is derived from the combination of two words: "blow" and "off".
The term "blow" dates back to Old English, where it was originally spelled "blawan". It has roots in the Proto-Germanic word "blæwan", meaning "to blow" or "to breathe". Over time, the meaning of "blow" expanded to include the act of expelling air forcefully or creating a gust of wind.
The word "off" can be traced back to Middle English, with its origins in Old English "of" or "off". It is related to the Proto-Germanic word "af", which means "away" or "apart". In this context, "off" refers to something being removed or separated.
