She came to the party with a friend.

I didn’t recognise the friend (that) she came with.

and the formal but clumsier ‘I didn’t recognise the

friend with whom she came’.

Prescriptive grammars, based on Latin, frown on sentences in which prepositions are isolated at the ends of sentences, though they are commonly found there in English.

2. Certain nouns and adjectives demand to be followed by particular prepositions, e.g.

a fall/rise/increase/decrease in (NP)

a relationship/connection with (NP)

furious about (NP = thing)

furious with (NP = person)

Different varieties of English prefer different prepositions to follow some adjectives, e.g. ‘different’:

My preference is different to/than/from yours.

Some prepositions attach to verbs, sometimes changing their meaning. For example:

to get = to obtain

to get up = to rise

to get in = to enter

to get to = to begin

In such cases some grammarians prefer to call the word forms adverbs or particles rather than prepositions, to indicate their function as part of the verb. Verbs that combine with one or more particles (e.g. put up with, fall out with, go off) are called phrasal verbs. However, other verbs are conventionally followed by particular prepositions, e.g.

to rely on

to agree with (person).
