Capable of being touched (8)
I believe the answer is:
tangible
'capable of being touched' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tangible that I've seen before include "Able to be felt" , "Actual" , "Bleating in clear and definite manner" , "Concrete - bleating (anag)" , "Material" .)
