Served, as did Edward on a court? (5)
I believe the answer is:
acted
'served as' is the definition.
(acting is a kind of serving as)
'edward on a court?' is the wordplay.
'edward' becomes 'Ed' (short for Edward).
'on' says to put letters next to each other.
'court?' becomes 'ct' (abbreviation used in road names).
'a'+'ct'='act'
'ed' after 'act' is 'ACTED'.
'did' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for acted that I've seen before include "Pretended" , "Played a 30ac" , "Behaved or played a part" , "appeared on stage" , "Feigned" .)
