What does signaling mean?
Signaling is the act of conveying information through a deliberate signal rather than through ordinary speech or writing. A signal may take the form of a gesture, facial expression, light, sound, electronic transmission, or written sign, and signaling can also be used figuratively to describe how people indicate intentions or conditions to one another. In biology and medicine, the term refers specifically to communication among cells through chemical messengers, receptors, and signaling pathways. The word often suggests intentional communication: someone who signals with a hand is making a deliberate request or warning, while deceptive signaling may involve creating a misleading impression. It is useful in both everyday and technical writing because it distinguishes the deliberate use of a signal from communication in general. The related verb describes the act of making such a communication, as in warning someone of danger or indicating that a service is operating.
The act or process of communicating information, a warning, or an intention through a signal.
"Her calm signaling told the crew that everything was under control."
The noun is common in general contexts and is also standard technical terminology in fields such as biology, medicine, and telecommunications.
To communicate a warning, intention, or instruction by making or sending a signal.
"She signaled to the driver to wait."
The verb can also mean to indicate or suggest something indirectly, as in “The results signal a change in public opinion.”
Rare and usually unnecessary; the noun is normally used in the singular or as an uncountable process.
"The recordings captured several distinct warning signallings."
From a raised hand to a hormone traveling through the body, signaling connects human gestures with the invisible messages that keep living systems coordinated.

Where does signaling come from?
The word ultimately derives from Latin signum, meaning a sign, mark, or signal. Through Old French, this developed into the English noun signal by the late 16th century, and signaling was formed as a derivative of that noun. English also has related forms such as sign, signature, and signify, which preserve the same older root.
