Big punch around lido mixed for tourist (12)
I believe the answer is:
holidaymaker
'for tourist' is the definition.
(synonyms)
'big punch around lido mixed' is the wordplay.
'big punch' becomes 'haymaker' (haymaker is a kind of punch. I am not sure about the 'big' bit.).
'around' means one lot of letters goes inside another.
'mixed' indicates anagramming the letters.
'lido' with letters rearranged gives 'olid'.
'haymaker' going around 'olid' is 'HOLIDAYMAKER'.
Can you help me to learn more?
(Other definitions for holidaymaker that I've seen before include "taking a well-earned break?" , "Tourist" , "person in resort" .)
