Translation:The buses often come by this station.
"Les bus passent souvent à cette station"
So, the plural for "le bus" seems to be "les bus" or "des bus", right? Would that be a mistake to use "les buses"?
The plural of 'le bus' is 'les bus' and the plural of 'un bus' is 'des bus'.
Words ending in 's' don't change in plural. So 'les buses' is incorrect. http://www.french-linguistics.co.uk/grammar/plural.shtml
