Psychic ability, for short (3)
I believe the answer is:
esp
'psychic ability for short' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for esp that I've seen before include "Apparent power to perceive things that others can't, initially" , "Extrasensory perception (abbrev.)" , "Apparent power to perceive things that others can't, in short" , "Second sight (abbr)" , "Initially, clairvoyance or telepathy" .)
