Lion country! (7)
I believe the answer is:
england
'lion country' is the definition.
'england' can be an answer for 'country' (England is an example). I am not sure about the 'lion' bit.
'lion country' is the wordplay.
'lion' becomes 'eng' (I can't justify this - if you can you should believe this answer much more).
'country' becomes 'land' (synonyms).
'eng'+'land'='ENGLAND'
Can you help me to learn more?
(Other definitions for england that I've seen before include "Lend nag (anag)" , "' - - expects' (Nelson)" , "Division of Great Britain" , "1A 30 [TEST TEAM]" , "Largest country in the UK" .)
