Beefcake covered with celery tips in big pieces (6)
I believe the answer is:
chunky
'beefcake covered with celery tips in big pieces' is the definition.
I can't tell whether this defines the answer.
'covered with celery tips in big pieces' is the wordplay.
'covered with' means one lot of letters goes inside another.
'tips' says to hollow out the word (remove centre letters) (just the outer letters of the world).
'in big pieces' becomes 'hunk' (I can't justify this - if you can you should believe this answer much more).
'celery' with its middle removed is 'cy'.
'cy' placed around 'hunk' is 'CHUNKY'.
Can you help me to learn more?
(Other definitions for chunky that I've seen before include "Short and broad" , "Short and thick" , "Bulky and thick" , "Thick - stout" , "Thick-set" .)
