colossal

I'm a little stuck... Click here to teach me more about this clue!

'huge' is the definition.
('colossal' can be a synonym of 'huge')

'company deficit a line shows' is the wordplay.
'company' becomes 'co' (abbreviation).
'deficit' becomes 'loss' (I've seen this before).
'a line shows' becomes 'al' (I am not sure about this - if you are sure you should believe this answer much more).
'co'+'loss'+'al'='COLOSSAL'

Can you help me to learn more?

(Other definitions for colossal that I've seen before include "Massive" , "Very big" , "Jumbo" , "Huge, immense" , "Mammoth" .)
