The word "signal" originated from the Old French "segnal" which derived from the Latin word "signum", meaning a sign, signal, or mark. "Signum" itself has Indo-European roots and can be traced back to the Proto-Indo-European root "*sekw-", meaning to follow or pursue. The word "signal" entered the English language in the 14th century with the meaning of a sign or indication, and later came to refer specifically to a gesture, sound, or action used to communicate a message.
