Understood how judge may appear after lawsuit's conclusion (7)
I believe the answer is:
twigged
'understood' is the definition.
(I've seen this before)
'how judge may appear after lawsuit's conclusion' is the wordplay.
'how judge may appear' becomes 'wigged' (judges often wear wigs).
'after' is a charade indicator (letters next to each other).
'conclusion' indicates one should take the final letters.
The last letter of 'lawsuit' is 't'.
'wigged' put after 't' is 'TWIGGED'.
(Other definitions for twigged that I've seen before include "understood" , "Got wise" , "caught on" , "Got the point" , "like the elder" .)
