Feeling generated by Ireland's third poet laureate (7)
I believe the answer is:
emotion
'feeling' is the definition.
(emotion is a kind of feeling)
'ireland's third poet laureate' is the wordplay.
'ireland's third' becomes 'e' (3rd letter of 'ireland').
'poet laureate' becomes 'Motion' (Sir Andrew Motion, UK Poet Laureate 1999 to 2009).
'e'+'motion'='EMOTION'
'generated by' is the link.
(Other definitions for emotion that I've seen before include "sense" , "Passion" , "Intuitive feeling" , "Intense feeling" , "Feeling of joy, love, hate etc" .)
