jesus, “on” the bus, “on” the train, and “on” the xxx, these are vessels or vehicles belonging to public transporting utility… of course, public transporting utility is usually “BIG”…
however, the most significant aspect for choosing “on” originally may be the following point:
the main floor of these “vessels” or “vehicles” is “high” comparing to the waiting passengers standing point before being aboard. people need to “step on the stairs” to get “up” to the main floor. when did people invent “bus”? actually, in the “old” days, people should have invented “get up the bus” instead, hahaha… please also note that people use “off the xxx” to indicate a passenger’s departure away from the vessel or vehicle.
next, let me present you a scenario as the following description.
if there is a very large jeep or hummer that is also very tall with a high floor above the ground,
then what phrase do you use to describe the “action or state of being aboard” such vehicle?
getting “on” the jeep or “in” the hummer? which one? or, what? or, there is some other phrase?
Not quite, Royd, it has to do with the size of the vehicle rather than whether it is public or private.
A taxi is public transport, but you would travel in a taxi, not on it!
I don’t quite follow what you are trying to say, but here most of the time we get on a bus, we travel on a bus (or by bus), we ride on a bus, we go somewhere on a bus, we arrive on a bus.
‘In a bus’ is used occasionally, but nowhere near as often as ‘on a bus’.
‘Stative’ verbs don’t usually take the progressive form because the verb itself describes a state which lasts all the time as with verbs like ‘know’ ‘understand’ and so on. The other verbs which are the opposite of stative verbs are called ‘dynamic’ because they express an action.
