Flyer right to have a drink (4)
I believe the answer is:
beer
'a drink' is the definition.
(I know that beer is a type of drink)
'flyer right to have' is the wordplay.
'right' indicates one should take the final letters (the letter on the right of the word).
'to' says to put letters next to each other (I've seen this in other clues).
'have' becomes 'bee' (I can't justify this - if you can you should give a lot more credence to this answer).
The last letter of 'flyer' is 'r'.
'r' after 'bee' is 'BEER'.
Can you help me to learn more?
(Other definitions for beer that I've seen before include "Brewery product" , "... this at pub?" , "Perhaps bitter" , "pint" , "Ale, lager etc" .)
