Beer with new king in joint (5)
I believe the answer is:
ankle
'joint' is the definition.
(joint of the body)
'beer with new king' is the wordplay.
'beer' becomes 'ale' (type of beer).
'with' is an insertion indicator.
'new' becomes 'n' (abbreviation as in New Testament NT).
'king' becomes 'K' (abbreviation for king in chess).
'n'+'k'='nk'
'ale' enclosing 'nk' is 'ANKLE'.
'in' is the link.
(Other definitions for ankle that I've seen before include "Joint between foot and leg" , "Lower leg joint" , "Foot-leg connector" , "Major foot joint" , "Narrow part of leg" .)
