Irish men should adopt the Italian sense of style (5)
I believe the answer is:
flair
'style' is the definition.
(I know that style can be written as flair)
'irish men should adopt the italian sense' is the wordplay.
I cannot quite understand how this works, but
'irish' could be 'ir' (abbreviation) and 'ir' is present in the answer.
'the italian' could be 'la' ('the' in Italian) and 'la' is found in the answer.
A single letter 'f' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for flair that I've seen before include "Style, talent" , "Faculty" , "Natural talent and aptitude" , "Intuitive discernment" , "skill" .)
