Trap seen, ran out! (7)
I believe the answer is:
ensnare
'trap' is the definition.
(I've seen this before)
'seen ran out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'seen'+'ran'='seenran'
'seenran' is an anagram of 'ENSNARE'.
(Other definitions for ensnare that I've seen before include "Catch as if in a trap or net" , "Capture, trap" , "Ambush" , "Ecstatic expression of feeling" .)
