Hot? Sample some lemonade sir, a blessing! (9)
I believe the answer is:
desirable
'hot?' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'sample some lemonade sir a blessing' is the wordplay.
'sample some' says the answer is hidden in the clue (I've seen 'sampling some' mean this).
'DESIRABLE' is hidden in the letters of 'lemonade sir a blessing'.
Can you help me to learn more?
(Other definitions for desirable that I've seen before include "Attractive" , "Sought-after - rebel aids (anag)" , "Alluring" , "Worth having" , "handsome maybe" .)
