Emotional poet in a mess after inhaling dope (10)
I believe the answer is:
passionate
'emotional' is the definition.
(associated in meaning)
'poet in a mess after inhaling dope' is the wordplay.
'mess' is an anagram indicator.
'after inhaling' means one lot of letters goes inside another.
'dope' becomes 'ass' (I've seen this in another clue).
'poet'+'in'+'a'='poetina'
'poetina' with letters rearranged gives 'pionate'.
'pionate' placed around 'ass' is 'PASSIONATE'.
(Other definitions for passionate that I've seen before include "enthusiastic" , "Easily moved" , "Showing intense feeling" , "Ardent" , "Having strong feelings" .)
