Dignity in Irish love for strange vista (8)
I believe the answer is:
'dignity' is the definition.
(I know that dignity can be written as gravitas)
'irish love for strange vista' is the wordplay.
'irish love' becomes 'gra' (I've seen this in another clue).
'for' means one lot of letters go next to another.
'strange' indicates an anagram.
'vista' anagrammed gives 'vitas'.
'in' is the link.
(Other definitions for gravitas that I've seen before include "Dignity of manner" , "serious quality" , "Weight" , "Dignity; air of seriousness" , "Seriousness - sobriety" .)
