Keen for action? (6,3)
I believe the answer is:
battle cry
'keen for action?' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'keen for action?' is the wordplay.
'keen' becomes 'cry' (keen can mean 'wail in grief').
'for' means one lot of letters go next to another (I've seen this in other clues).
'action?' becomes 'battle' (military action).
'cry' after 'battle' is 'BATTLE-CRY'.
Can you help me to learn more?
(Other definitions for battle cry that I've seen before include "Martial slogan" , "Geronimo, for example" , "jingoistic shout" , "Slogan (for those going into a fight?)" .)
