Three soldiers fought 'among' themselves. (This sounds correct.)<br/><br/><br/>The fight was between Joe, Mike and Steve. ('Between' or 'among'? More than two people involved, but 'between' sounds more correct to my ear.)<br/><br/><br/>The contract was between the buyer, seller and mortgagor.<br/><br/>(Again, three people but 'between' – not 'among' – sounds like the better choice here.)<br/><br/><br/>Thank you.
