A prepositional phrase is made up of a preposition and a noun phrase. We use prepositional phrases for many purposes, for example:

- as adverbials of time and place:

We will be back in a few days.
They drove to Glasgow

.- as a postmodifier in a noun phrase:

Helen is the girl in the red dress
We’ve got a new television with a thirty one inch screen.

- to show who did something:

The lion was killed by the hunter
I saw a wonderful painting by Van Gogh

- with double object verbs like give and get:

We gave five pounds to the woman on the corner.
They got a drink for me.

- after certain verbs, nouns and adjectives:

The book belongs to me.
I had an argument with my brother.
I feel sorry for you.




I'd like to know the difference between control of and control over.
For example, loss of human control of or over machines.

Hello Petals,

The first thing I'd recommend is that you read through the entry for 'control' (especially the one in which it is a noun) in the dictionary, looking carefully at the example sentences. Most of the time, 'of' or 'over' are used depending on what verb collocates with the word 'control'. In the case of the verb 'lose' (as in your example), both 'of' and 'over' are possible, though I think 'over' is better here. This is because 'of' tends to be used when the object controlled is something that has no volition of its own (e.g. a car or plane), but when the object has some kind of volition (e.g. a child or maverick robot), then 'over' is used.

Hello . I want to ask : how we can negate prepositional phrase. thank you.

Hello rastak keen,

Can you give an example? Off the top of my head, I can't think of a way to negate a prepositional phrase other than negating the verb or another part of the sentence.

He is flying to London. He flew for London.
I think the above sentences are gramatically correct.
Can't I say 'he flew to London.' Is it wrong then? Could you explain this to me please? I was told 'to' means direction and 'for' location.
Thank you.
