The word "control" originated from the late Middle English term "controilen", which was derived from the Old French word "contreroller". The Old French term was a combination of the prefix "contre-" meaning "against" and "roller", meaning "to roll" or "to check". This original meaning of "contreroller" was to "examine or verify by rolling a register". Over time, this evolved to refer to checking or regulating something.
The word "message" comes from the Latin term "missus" which means "a sending" or "something sent". It entered the English language in the 14th century, originally referring to a messenger or a communication sent.
When combined, the term "control message" refers to a communication or a message that is sent to regulate or manage something.
