Boy emptied ladleful round yard (5)
I believe the answer is:
lloyd
'boy' is the definition.
'emptied ladleful round yard' is the wordplay.
'emptied' means to remove the middle letters.
'round' becomes 'o' (o is a circular letter).
'yard' becomes 'yd' (abbreviation).
'ladleful' with its middle removed is 'll'.
'll'+'o'+'yd'='LLOYD'
(Other definitions for lloyd that I've seen before include "Andrew -- Webber, composer" , "David -- George, PM 1916-22" , "David - George, British PM nineteen sixteen to nineteen twenty two" , "Christopher - - , garden expert" , "Welsh family name" .)
