Figure observed with episode screened (9)
I believe the answer is:
seventeen
'figure' is the definition.
(I've seen this before)
'observed with episode screened' is the wordplay.
I cannot quite see how this works, but
'episode' could be 'event' (I've seen this before) and 'event' is found in the answer.
'observed' could be 'seen' (synonyms) and 'seen' is found within the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for seventeen that I've seen before include "Figure" , "Quite a few" , "odd number" , "next clue" , "XVII" .)
