Revolutionary gladiators lost out in this North African city (6)
I believe the answer is:
agadir
'african city' is the definition.
(I've seen this before)
'revolutionary gladiators lost out' is the wordplay.
'revolutionary' indicates anagramming the letters.
'out' is a deletion indicator.
'gladiators' with 'lost' taken away is 'gadiar'.
'gadiar' is an anagram of 'AGADIR'.
'in this north' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for agadir that I've seen before include "City in Morocco" , "African city" , "Moroccan port" , "Moroccan seaport" , "Port in south-west Morocco" .)
