What is difference between phrasal preposition and prepositional phrase?

A phrasal preposition consists of more than one word, like 'in front of', 'on behalf of'.

A prepositional phrase is a preposition (simple or phrasal) + noun phrase object: 'on the desk', 'in front of the fireplace'.

Your explanations are always fruitful to me. I always get some new idea from your answer.

What's a pure preposition?


Phrasal prepostion= only preposition with more than one word( Whole combination can be considered as a single preposition).

1.We put off washing the dishes.

2.A button came off my shirt.

In (1) "off" as an adverb.

In (2) "off" as a preposition.

Am I right?

Ah, I see. The group of words function as a single preposition, but they can be dissected into:

Adverb + preposition -- 'instead of', 'due to', 'except for'


Preposition + noun + preposition -- 'in front of', 'on behalf of', 'in spite of'

(1) is an adverbial 'off', and I would call it an adverb in (2) also-- the 'of' has been elided:

'A button came off (of) my shirt.'
'A button came off in the laundromat.'

There may be another opinion on that one.
