A well-known figure in EastEnders (3)
I believe the answer is:
ten
'a well-known figure' is the definition.
'ten' can be an answer for 'figure' (ten is a number or figure). I'm not certain of the 'a well-known' bit.
'in eastenders' is the wordplay.
'in' says the answer is hidden in the clue.
'TEN' is hidden in the letters of 'eastenders'.
Can you help me to learn more?
(Other definitions for ten that I've seen before include "Dudley Moore/Bo Derek film" , "Base of decimal system" , "Half a score" , "X-WORD" , "How many" .)
