Trapped Yank nears end (8)
I believe the answer is:
ensnared
'trapped' is the definition.
('ensnare' can be a synonym of 'trap')
'yank nears end' is the wordplay.
'yank' is an anagram indicator ('yank' can mean to pull around and move).
'nears'+'end'='nearsend'
'nearsend' is an anagram of 'ENSNARED'.
(Other definitions for ensnared that I've seen before include "Caught in a trap" , "Trapped" .)
