Have a break, after four attempts to shoot? (4,4)
I believe the answer is:
take five
'have a break' is the definition.
(I've seen this before)
'four attempts to shoot?' is the wordplay.
'four attempts' becomes 'five' (I can't explain this - if you can you should believe this answer much more).
'to' says to put letters next to each other (I've seen this in other clues).
'shoot?' becomes 'take' (synonyms).
'five' after 'take' is 'TAKE FIVE'.
'after' is the link.
Can you help me to learn more?
(Other definitions for take five that I've seen before include "Invitation to break" , "Leave one of half a dozen" , "Have a short break (by Brubeck?)" , "Enjoy the rest!" , "Have a break (colloq.)" .)
