Memorable uniform put on heads of the finest university lecturers (8)
I believe the answer is:
eventful
'memorable' is the definition.
(thesaurus)
'uniform put on heads of the finest university lecturers' is the wordplay.
'uniform' becomes 'even' (I've seen this before**).
'put on' says to put letters next to each other.
'heads of' says to take the initial letters.
The first letters of 'the finest university lecturers' is 'tful'.
'even'+'tful'='EVENTFUL'
(Other definitions for eventful that I've seen before include "Action-packed" , "Memorable; momentous" , "Full of incidents, momentous" , "Full of noteworthy incidents" , "Full of incident, not dull" .)
