Game in which ale served up for pirate (10)
I believe the answer is:
freebooter
'pirate' is the definition.
(thesaurus)
'game in which ale served up' is the wordplay.
'game' becomes 'footer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in which' indicates putting letters inside.
'ale' becomes 'beer' (I've seen this before).
'served up' says the letters should be written in reverse.
'beer' backwards is 'reeb'.
'footer' placed around 'reeb' is 'FREEBOOTER'.
'for' is the link.
Can you help me to learn more?
(Other definitions for freebooter that I've seen before include "Person roaming for plunder" , "Plunderer" , "Lawless adventurer" , "I used to steal" , "Lawless person" .)
