Elderly drinking wine endlessly? It's okay (6)
I believe the answer is:
agreed
'okay' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'elderly drinking wine endlessly? it's' is the wordplay.
'elderly' becomes 'aged' (synonyms).
'drinking' indicates putting letters inside (inserted letters are consumed or drunk).
'wine endlessly?' becomes 'r' (I can't explain this - if you can you should believe this answer much more).
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'r'+'e'='re'
'aged' enclosing 're' is 'AGREED'.
Can you help me to learn more?
(Other definitions for agreed that I've seen before include "Harmonised" , "Assented, acquiesced" , "Accepted; tallied" , "Consented, settled" , "In harmony" .)
