Terribly laden gent snarled (9)
I believe the answer is:
entangled
'snarled' is the definition.
('entangle' can be a synonym of 'snarl')
'terribly laden gent' is the wordplay.
'terribly' indicates an anagram.
'laden'+'gent'='ladengent'
'ladengent' with letters rearranged gives 'ENTANGLED'.
(Other definitions for entangled that I've seen before include "Confusedly twisted" , "caught" , "snarled up" , "Involved in complications" , "Intertwined; entrapped" .)
