The German going round skating area with tippler (7)
I believe the answer is:
drinker
'tippler' is the definition.
(I've seen this before)
'the german going round skating area' is the wordplay.
'the german' becomes 'der' ('the' in German).
'going round' means one lot of letters goes inside another (some letters go around others).
'skating area' becomes 'rink' (I've seen this before).
'der' placed around 'rink' is 'DRINKER'.
'with' acts as a link.
(Other definitions for drinker that I've seen before include "Inebriate" , "Imbiber, toper" , "Tippler" , "Consumer of liquid, probably alcohol" .)
