Revered figure in holding company (4)
I believe the answer is:
icon
'revered figure' is the definition.
(an icon is a celebrated figure)
'in holding company' is the wordplay.
'holding' means one lot of letters goes inside another.
'company' becomes 'co' (abbreviation).
'in' placed around 'co' is 'ICON'.
(Other definitions for icon that I've seen before include "Image - sex symbol" , "Devotional painting" , "Religious image or computer symbol" , "Sacred painting or representitive figure" , "work of art" .)
