What does involuntariness mean?
Involuntariness is the noun form of “involuntary” and names the condition of an action, movement, sensation, or response occurring without conscious intention or deliberate control. It is especially useful when discussing reflexes, habitual behavior, involuntary expressions, or actions performed without awareness. The word can emphasize either the absence of intention or the lack of voluntary control, although these can overlap. In everyday speech, “involuntary” is normally preferred: people speak of an “involuntary smile” or “involuntary laughter” more often than of the “involuntariness” of a smile or laughter. In scientific, medical, psychological, and philosophical contexts, however, the noun is valuable for describing a broader condition or property rather than a particular instance. Its clearest distinction is from “voluntariness”: voluntariness implies deliberate intention and control, while involuntariness describes behavior that arises without them.

Where does involuntariness come from?
“Involuntariness” was formed in English by adding the noun-forming suffix “-ness” to “involuntary.” “Involuntary” comes from Latin involuntarius, built from the negative prefix in- and voluntarius, meaning willing or free to choose. The same Latin root voluntas, meaning “will” or “choice,” also gives English words such as “voluntary,” “voluntary,” and “volition.”
