Desire shown where t-shirt ripped (6)
I believe the answer is:
thirst
'desire' is the definition.
(thirsting is a kind of desiring)
't-shirt ripped' is the wordplay.
'ripped' indicates an anagram.
'shirt' is an anagram of 'hirst'.
't'+'hirst'='THIRST'
'shown where' is the link.
(Other definitions for thirst that I've seen before include "Craving for liquid" , "Dryness" , "T-shirt (anag)" , "Strong need for drink" , "Want of drink" .)
