Harsh part of text remembered (7)
I believe the answer is:
extreme
'harsh' is the definition.
(I've seen this before)
'part of text remembered' is the wordplay.
'part of' indicates a hidden word.
'EXTREME' is hidden within 'text remembered'.
(Other definitions for extreme that I've seen before include "Furthest or highest degree of something" , "Last" , "Meet Rex (anag.)" , "Severe; radical" , "Very intense - way-out" .)
