Note on type of wine that's past its best (5)
I believe the answer is:
tired
'past its best' is the definition.
I can't tell whether this defines the answer.
'note on type of wine' is the wordplay.
'note' becomes 'ti' (musical note, as in do re mi so fa la ti do).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'type of wine' becomes 'red' (I've seen this in another clue).
'ti'+'red'='TIRED'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for tired that I've seen before include "Played out" , "Physically or mental weary" , "getting bored" , "knackered" , "Zonked" .)
