A popular figure from the lido (4)
I believe the answer is:
idol
'a popular figure' is the definition.
'idol' can be an answer for 'figure' (I've seen this before). I'm not certain of the 'a popular' bit.
'from the lido' is the wordplay.
'from' is an anagram indicator (from the letters).
'lido' is an anagram of 'IDOL'.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "A graven image or object of adoration" , "Sacred image" , "One much admired" , "'Worshipped object, admired person (4)'" , "Worshipped figure (not painting); revered person" .)
