Massive company deficit facing almost everybody (8)
I believe the answer is:
colossal
'massive' is the definition.
(thesaurus)
'company deficit facing almost everybody' is the wordplay.
'company' becomes 'co' (abbreviation).
'deficit' becomes 'loss' (I've seen this before).
'facing' says to put letters next to each other.
'almost' means to remove the last letter (most of the word but not all of it).
'everybody' becomes 'all' (I've seen this before).
'all' with its last letter removed is 'al'.
'co'+'loss'+'al'='COLOSSAL'
(Other definitions for colossal that I've seen before include "Huge, vast" , "Very big" , "Mammoth" , "Great" , "Stupendous" .)
