Overweight English lot (4)
I believe the answer is:
fate
'lot' is the definition.
('fate' can be a synonym of 'lot')
'overweight english' is the wordplay.
'overweight' becomes 'fat' (I've seen this before).
'english' becomes 'e' (abbreviation).
'fat'+'e'='FATE'
(Other definitions for fate that I've seen before include "Lot -- doom" , "Predestiny" , "Clotho, Lachesis or Atropos" , "Destiny, kismet" , "What must be" .)
