Point also to Macron in Irish assembly (6)
I believe the answer is:
detail
'point' is the definition.
(I know that point can be written as detail)
'to macron in irish assembly' is the wordplay.
'to macron' becomes 'et' (I am not sure about this - if you are sure you should believe this answer much more).
'in' is an insertion indicator.
'irish assembly' becomes 'dail' (I've seen this before).
'et' placed within 'dail' is 'DETAIL'.
'also' acts as a link.
Can you help me to learn more?
(Other definitions for detail that I've seen before include "Tailed into particulars" , "Small part of the whole" , "Enumerate or itemise" , "Dilate with individual item" , "Particular - military detachment" .)
