Sensitive English poet originally appointed Laureate (9)
I believe the answer is:
emotional
'sensitive' is the definition.
(thesaurus)
'english poet originally appointed laureate' is the wordplay.
'english' becomes 'E' (abbreviation).
'poet' becomes 'motion' (former Poet Laureate Andrew Motion).
'originally' says to take the initial letters.
The first letters of 'appointed laureate' is 'al'.
'e'+'motion'+'al'='EMOTIONAL'
(Other definitions for emotional that I've seen before include "Impassioned - excitable" , "Worked up, upset" , "Touching" , "Arousing strong feeling" , "Arousing intense feelings" .)
