Walk to lop off top of daisy (4)
I believe the answer is:
plod
'walk' is the definition.
(I know that plod is a type of walk)
'lop off top of daisy' is the wordplay.
'off' indicates an anagram.
'top of' suggests taking the first letters.
The initial letter of 'daisy' is 'd'.
'lop' with letters rearranged gives 'plo'.
'plo'+'d'='PLOD'
'to' acts as a link.
(Other definitions for plod that I've seen before include "Walk heavily (like a policeman?)" , "Fuzzy type" , "Walk with heavy steps" , "Copper" , "Walk laboriously, trudge" .)
