Going to the net I foozled again, on the whole (6)
I believe the answer is:
entire
'whole' is the definition.
(similar in meaning)
'going to the net i foozled again on the' is the wordplay.
I cannot quite see how this works, but
an anagram of 'net' is 'ent' which is within the answer.
'i' is within the answer.
'again' could be 're' and 're' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for entire that I've seen before include "porter" , "everything" , "Unmitigated" , "Envelope" , "Whole; absolute" .)
