Again circulate glowing eulogy about one son (12)
I believe the answer is:
redistribute
'again circulate' is the definition.
('distribute' can be a synonym for 'circulate' so perhaps 'redistribute' is OK for 'again circulate')
'glowing eulogy about one son' is the wordplay.
'glowing' becomes 'red' (red hot).
'eulogy' becomes 'tribute' (a tribute at a funeral).
'about' means one lot of letters go next to another.
'one' becomes 'i' (Roman numeral).
'son' becomes 's' (genealogical abbreviation for son).
'i'+'s'='is'
'tribute' after 'is' is 'istribute'.
'red'+'istribute'='REDISTRIBUTE'
(Other definitions for redistribute that I've seen before include "Allocate differently" , "dish out again" , "Share out differently" .)
