Complete anger after getting net tangled (6)
I believe the answer is:
entire
'complete' is the definition.
(synonyms)
'anger after getting net tangled' is the wordplay.
'anger' becomes 'ire' (ire is intense rage).
'after getting' is a charade indicator (letters next to each other).
'tangled' is an anagram indicator.
'net' is an anagram of 'ent'.
'ire' put after 'ent' is 'ENTIRE'.
(Other definitions for entire that I've seen before include "Whole; unbroken" , "everything" , "excluding nothing" , "With no part left out" , "Unharmed - total" .)
