Appropriate for poet to admit who he is (7)
I believe the answer is:
impound
'appropriate for poet to admit who he is' is the definition.
'impound' can be an answer for 'appropriate' (thesaurus). I am not certain of the rest of the definition.
'appropriate for poet' is the wordplay.
'appropriate for' becomes 'im' (I am not sure about this - if you are sure you should believe this answer much more).
'poet' becomes 'pound' (I've seen this before).
'im'+'pound'='IMPOUND'
Can you help me to learn more?
(Other definitions for impound that I've seen before include "Confiscate" , "Seize (goods) legally" , "Seize goods for an infringement of the law" , "appropriate" , "Take legal possession of" .)
