Preside over meeting daily, about one (5)
I believe the answer is:
chair
'preside over' is the definition.
(I've seen this before)
'daily about one' is the wordplay.
'daily' becomes 'char' (both can mean a cleaner).
'about' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'char' going around 'i' is 'CHAIR'.
'meeting' acts as a link.
(Other definitions for chair that I've seen before include "Head of a university faculty or department" , "Movable seat" , "Academic position" , "Get seat" , "Single seat" .)
