Wander about with a doctor recently taken on by university (8)
I believe the answer is:
ambulate
'wander about' is the definition.
'a doctor recently taken on by university' is the wordplay.
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus**).
'recently' becomes 'late' (I've seen this in other clues).
'taken on by' means one lot of letters go next to another.
'university' becomes 'u'.
'late' put after 'u' is 'ulate'.
'a'+'mb'+'ulate'='AMBULATE'
'with' is the link.
(Other definitions for ambulate that I've seen before include "Go for a stroll" , "Walk (technical)" .)
