Northern Irish perhaps lifting article that’s divine (7)
I believe the answer is:
angelic
'divine' is the definition.
(like an angel)
'northern irish perhaps lifting article' is the wordplay.
'northern' shows that the letters should be reversed in order (in a down clue, letters go up or 'north').
'irish' becomes 'cil' (I can't justify this - if you can you should give a lot more credence to this answer).
'perhaps' becomes 'eg' (for example).
'lifting' is a charade indicator (letters next to each other).
'article' becomes 'an' (indefinite article).
'cil'+'eg'='cileg'
'cileg' in reverse letter order is 'gelic'.
'gelic' after 'an' is 'ANGELIC'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for angelic that I've seen before include "Divine" , "sweet-natured too" , "Heavenly - entrancing" , "Very well behaved" , "I glance (anag.)" .)
