Cheat, only to have university raising question (5)
I believe the answer is:
doubt
'question' is the definition.
(I've seen this before)
'cheat only to have university raising' is the wordplay.
'cheat' becomes 'do'.
'only' becomes 'tb' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to have' means one lot of letters go next to another.
'university' becomes 'u'.
'raising' is a reversal indicator.
'tb'+'u'='tbu'
'tbu' reversed gives 'ubt'.
'do'+'ubt'='DOUBT'
Can you help me to learn more?
(Other definitions for doubt that I've seen before include "Question the truth or accuracy of" , "One certainly can't have it" , "Be uncertain about or consider unlikely" , "Feel uncertain about" , "Have reservations or be uncertain about" .)
