We're told the fellow's going to part of Oxford? (4)
I believe the answer is:
heel
'part of oxford?' is the definition.
'heel' can be an answer for 'part' (heel is a kind of part). I'm not sure about the 'of oxford?' bit.
'we're told the fellow's' is the wordplay.
I cannot really see how this works, but
'fellow' could be 'he' ('he' refers to a man) and 'he' is located in the answer.
The remaining letters 'el' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'going to' is the link.
Can you help me to learn more?
(Other definitions for heel that I've seen before include "swine" , "Achilles's weak spot" , "Lean - back of foot" , "I might let down" , "secure ball" .)
