Buses – Quick Answer

  • Buses is the correct plural form of the noun “bus.”
  • Busses is rarely used and is mostly a variant spelling in non-standard usage.
  • When to use:
    • Always use buses in formal and standard English.

The Origin of Buses

The word “bus” originated in the early 19th century, derived from the Latin word “omnibus”, which means “for all.” This term was used to describe a vehicle that was intended to carry multiple passengers, a predecessor to the modern bus.

As the word “bus” became more common, the plural form followed the standard English rule of adding -es to words that end in -s, -x, -z, -ch, or -sh (such as boxes, taxes, or matches). Thus, buses became the accepted plural form.
