Hamlet going round clubs and disco? (5)
I believe the answer is:
dance
'disco?' is the definition.
(I've seen this in other clues)
'hamlet going round clubs' is the wordplay.
'hamlet' becomes 'dane' (Hamlet is a famous Dane).
'going round' means one lot of letters goes inside another (some letters go around others).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'dane' enclosing 'c' is 'DANCE'.
'and' acts as a link.
(Other definitions for dance that I've seen before include "Bop" , "See 4" , "Flamenco, perhaps" , "bolero, for example" , "Social gathering" .)
