Liberal bobby is entering Oxford University (7)
I believe the answer is:
copious
'liberal' is the definition.
(thesaurus)
'bobby is entering oxford university' is the wordplay.
I cannot really see how this works, but
'oxford' could be 'ou' (abbreviation for Oxford University) and 'ou' is found within the answer.
'is' is found in the answer.
The remaining letters 'cop' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for copious that I've seen before include "Abundant in quantity" , "Many" , "Providing loads of" , "Plentiful, existing in large amounts" , "abundance" .)
