Where the figure's concerned, a bit fattening? (3)
I believe the answer is:
ten
'where the figure's concerned' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'a bit fattening?' is the wordplay.
'a bit' indicates the answer is hidden within the clue (the answer is formed by a bit of the clue).
'TEN' can be found hidden inside 'fattening'.
Can you help me to learn more?
(Other definitions for ten that I've seen before include "PM's address, Downing St" , "Cardinal number" , "How many" , "Very young" , "Five times two" .)
