insensible
Lacking all sensation
Insensible means unable to feel or perceive.
Someone knocked unconscious is insensible to their surroundings: He lay insensible on the pavement.
The word also describes gradual changes too subtle to detect: an insensible shift in public opinion.
In older usage, insensible meant unaware or indifferent: insensible to the dangers ahead.
The word carries a formal, somewhat literary tone.
