Left, with married buffoon, for the continent, say (8)
I believe the answer is:
landmass
'the continent say' is the definition.
(continent is a kind of landmass)
'left with married buffoon' is the wordplay.
'left' becomes 'l' (common abbreviation).
'with' becomes 'and' (I've seen this before**).
'married' becomes 'm'.
'buffoon' becomes 'ass' (I've seen this before).
'l'+'and'+'m'+'ass'='LANDMASS'
'for' is the link.
(Other definitions for landmass that I've seen before include "Asia, say" , "Eg, a continent" , "Huge area" .)
