Not broken and not disheartened in Ireland (6)
I believe the answer is:
entire
'not broken' is the definition.
(I've seen this in another clue)
'not disheartened in ireland' is the wordplay.
'disheartened' says to hollow out the word (remove centre letters) (the middle or heart is removed).
'in' means one lot of letters goes inside another.
'ireland' becomes 'eire' (poetic name for Ireland).
'not' with its centre removed is 'nt'.
'nt' going within 'eire' is 'ENTIRE'.
'and' acts as a link.
(Other definitions for entire that I've seen before include "outright" , "Unmitigated" , "Whole - undamaged" , "Whole; unbroken" , "Whole and complete" .)
