Rick takes Romeo into the country (6)
I believe the answer is:
sprain
'rick' is the definition.
(I know that rick can be written as sprain)
'romeo into the country' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'into' means one lot of letters goes inside another.
'the country' becomes 'Spain' (Spain is an example).
'r' placed within 'spain' is 'SPRAIN'.
'takes' acts as a link.
(Other definitions for sprain that I've seen before include "Muscle injury caused by wrench." , "unwelcome twist" , "Injure joint by wrenching it violently" , "Wrench (limb)" , "Turn" .)
