Tutor upset about abuse (7)
I believe the answer is:
torture
'abuse' is the definition.
(torture is a kind of abuse)
'tutor upset about' is the wordplay.
'upset' is an anagram indicator.
'about' becomes 're' (regarding**).
'tutor' anagrammed gives 'tortu'.
'tortu'+'re'='TORTURE'
(Other definitions for torture that I've seen before include "Inflict pain to extract information" , "Infliction of physical or mental suffering" , "Infliction of great suffering" , "Torment" , "Extreme pain" .)
