The word "shut off" is formed by combining two separate words: "shut" and "off".
The word "shut" came from the Old English word "scyttan" which meant "to close" or "to block". It can be traced back to the Proto-Germanic word "skutjaną" which carried a similar meaning.
The word "off" originated from the Old English word "of" or "offa", which indicated the action of separation or removal. It ultimately comes from the Proto-Germanic word "af" with the same meaning.
When these two words are combined into "shut off", the phrase signifies the act of closing or blocking something, while simultaneously separating it or removing access.
