Lager top drinks Irish broadcaster loved (7)
I believe the answer is:
hearted
'loved' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'lager top drinks irish broadcaster' is the wordplay.
'lager top' becomes 'head' (I can't explain this - if you can you should give a lot more credence to this answer).
'drinks' indicates putting letters inside (inserted letters are consumed or drunk).
'irish broadcaster' becomes 'RTE' (national broadcaster of Ireland).
'head' enclosing 'rte' is 'HEARTED'.
Can you help me to learn more?
(Another definition for hearted that I've seen is " Casually loved".)
