orinoco

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

'major river' is the definition.
(South American river)

'men in company crossing over' is the wordplay.
'men in' becomes 'orin' (I can't justify this - if you can you should believe this answer much more).
'company' becomes 'co' (abbreviation).
'crossing' is an insertion indicator.
'over' becomes 'o' (cricket abbreviation).
'orin'+'co'='orinco'
'orinco' placed around 'o' is 'ORINOCO'.

Can you help me to learn more?
