I clear out a small cake (6)
I believe the answer is:
eclair
'a small cake' is the definition.
'eclair' can be an answer for 'cake' (I've seen this before). I'm not sure about the 'a small' bit.
'i clear out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'i'+'clear'='iclear'
'iclear' with letters rearranged gives 'ECLAIR'.
Can you help me to learn more?
(Other definitions for eclair that I've seen before include "I clear off with thin chocolate cake" , "Finger-shaped, chocolate-iced, cream-filled cake" , "Cream bun" , "A relic (anag)" , "Food" .)
