Beberapa kata yang serupa dalam struktur dan maknanya tersebut antara lain: after, before, since, dan until.  apa yg membedakan kata kata tersebut yg merupakan

preposition = kata depan
conjunction = kata hubung

cara paling gampang untuk membedakannya adalah, preposition diikuti oleh kata benda  dan conjunction diikuti oleh klausa/v-ing

the traffic light is before the restaurant = preposition
