Show a piece of cake getting cut before presents (10)
I believe the answer is:
eastenders
'show' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'a piece of cake getting cut before presents' is the wordplay.
'a piece of cake' becomes 'easy' (I've seen this before).
'getting cut' means to remove the last letter.
'before' means one lot of letters go next to another.
'presents' becomes 'tenders' (tendering is a kind of presenting).
'easy' with its final letter taken away is 'eas'.
'eas'+'tenders'='EASTENDERS'
Can you help me to learn more?
(Other definitions for eastenders that I've seen before include "Soap, for example" , "Cockneys" , "BBC TV series" , "TV programme" , "TV soap" .)
