When the accompanying word introduces a prepositional phrase, it is classified as a preposition. When it does not, it is a particle. For example (phrasal verbs shaded):
- Wipe that paint off the wall. (In this example, the prepositional phrase is off the wall. The word off is a preposition.)
- Stop showing off. (Here, off is a particle.)
Don't Write Get Off OfWith verbs like to get off, to live off, and to go off, there is no need to add of. With these verbs (called phrasal verbs), the off acts as a preposition. There is no need to add your own preposition (i.e., don't write off of). For example:
- Get off the table.
- Get off of the table.
- She lived off the land.
- She lived off of the land.
- She is going off you.
- She is going off of you.
