Some target! Ring tavern queen! (5)
I believe the answer is:
inner
'some target ring' is the definition.
'inner' can be an answer for 'ring' (I've seen this before). I am unsure of the 'some target' bit.
'tavern queen' is the wordplay.
'tavern' becomes 'inn' (I've seen this in another clue).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'inn'+'er'='INNER'
Can you help me to learn more?
(Other definitions for inner that I've seen before include "Target area" , "Region around bullseye" , "It's next to the bull on the board" , "Esoteric" , "Located inward" .)
