During dry spell, love going for a drink (7)
I believe the answer is:
draught
'a drink' is the definition.
(draught is a kind of drink)
'during dry spell love going for' is the wordplay.
'during' indicates putting letters inside.
'dry spell' becomes 'drought' (a period of low rainfall).
'love' becomes 'o' (love means zero in tennis).
'going' indicates named letters should be taken away.
'for' becomes 'a' (I can't justify this - if you can you should believe this answer much more).
'drought' with 'o' taken out is 'drught'.
'drught' placed around 'a' is 'DRAUGHT'.
Can you help me to learn more?
(Other definitions for draught that I've seen before include "Alcohol drawn from a keg" , "man that may be crowned" , "drink needed" , "(Of beer) sold from the cask" , "Water depth; served from a cask" .)
