End of bottle – setter’s last in store for drinking session? (7)
I believe the answer is:
teatime
'drinking session?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'end of bottle setter's last in store' is the wordplay.
'end of bottle' becomes 'teat' (I can't explain this - if you can you should give a lot more credence to this answer).
'setter's' becomes 'I'm' (I am - referring to the crossword setter).
'last in' indicates one should take the final letters.
The last letter of 'store' is 'e'.
'teat'+'im'+'e'='TEATIME'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for teatime that I've seen before include "When cakes are eaten" , "When cake might be had" , "Clap" , "Afternoon meal period" , "Four o'clock?" .)
