Thanks Greg.
A long time ago, a stove denoted a room heating device like a pot belly stove or the much earlier Franklin Stove. The early term Cook Stove shows that it was a type of stove not meant solely for heating. A range was generally meant in the US as the term for a cooking stove that has an oven and a flat top containing burners or heating elements for surface cooking and I guess the term started with coal and wood cooking stoves because I have heard or read the term coal range to describe certain old stoves. I do not know if the broad, flat tops of these were somehow equated with the open range lands in America or if "range" came to be applied to kitchen stoves in some other way. In cookbooks and manuals for electric ranges, I have seen the term "range-top cooking." I have just heard the terms gas stove and electric range more commonly used as I was growing up, but maybe that was from older people for whom "range" was a more widely used term.
I will look through some of my owner's manuals to see if a hint lies there.
