Fit to pulp pine ash (2,5)
I believe the answer is:
in shape
'fit' is the definition.
(I've seen this in another clue)
'pulp pine ash' is the wordplay.
'pine ash' anagrams to 'IN SHAPE'.
However, I am not sure how this is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for in shape that I've seen before include "fit" , "trim" .)
