Relating to perception or knowledge that exists outside or beyond the normal five senses.
From Latin 'extra' (outside) + 'sensorial' (relating to the senses, from 'sensus' meaning sensation). A formal variant emphasizing the sensory apparatus itself.
While 'extrasensory' is the common term for ESP or psychic abilities, 'extrasensorial' is the fancier scientific word—though neither has been proven to actually exist in controlled experiments despite decades of research.
