Thin man being tipped (6)
I believe the answer is:
leaned
'tipped' is the definition.
('lean' can be a synonym of 'tip')
'thin man' is the wordplay.
'thin' becomes 'lean' (synonyms).
'man' becomes 'ed' (short for Edward).
'lean'+'ed'='LEANED'
'being' is the link.
(Other definitions for leaned that I've seen before include "Sloped or rested against" , "Listed" , "Inclined, bent towards" , "Rested against as for support" , "Sloped, inclined" .)
