Poet agreed terms without hesitation (5)
I believe the answer is:
yeats
'poet' is the definition.
(I know that Yeats is a poet)
'agreed terms without hesitation' is the wordplay.
'agreed' becomes 'yea' (I can't justify this - if you can you should believe this answer much more).
'without' suggests deleting specific letters.
'hesitation' becomes 'erm'.
'terms' with 'erm' taken out is 'ts'.
'yea'+'ts'='YEATS'
Can you help me to learn more?
(Other definitions for yeats that I've seen before include "W. B. -- , Irish poet/dramatist" , "Irish poet and dramatist, d. 1939" , "W B . . . . ., great Irish poet" , "Irish poet, 1923 Nobel Prize winner" , "William Butler .. . . ., Nobel-winning poet" .)
