Fleas around small cake - that needs to go again (5,5)
I believe the answer is:
false start
'needs to go again' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'fleas around small cake' is the wordplay.
'around' indicates an anagram.
'small cake' becomes 'start' (I am not sure about this - if you are sure you should believe this answer much more).
'fleas' is an anagram of 'false'.
'false'+'start'='FALSE START'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for false start that I've seen before include "In which runner is seen to have jumped the gun" , "may lead to total recall" , "In which someone jumps the gun" , "Unsuccessful beginning" .)
