Buses or Busses?

Busses has not been widely accepted as the plural of bus since the 1900s. In modern-day English, buses is the accepted plural of bus.

Confusion arises not only because of the historical plural busses but also because buses could feasibly be pronounced booses and so some writers, knowing how buses should be pronounced, opt for busses.

Of note, busses is the plural of buss (a North American term for a kiss).
