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' suggests removing the centre (the middle or heart is removed).
'in' indicates putting letters inside.
'ireland' becomes 'eire' (poetic name for Ireland).
'not' with its centre removed is 'nt'.
'nt' inserted into 'eire' is 'ENTIRE'.
'and' is the link.
(Other definitions for entire that I've seen before include "outright" , "Unmitigated" , "Whole - undamaged" , "Whole; unbroken" , "Whole and complete" .)
