Prepositions and relative clauses

A relative pronoun can be the object of a preposition: 
I found the keys which I was looking for.

That´s the woman who(m) I´m in love with.
  • In informal English we usually put the preposition at the end of the relative clause and we omit the relative pronoun: 
I found the keys I was looking for

That´s the woman I´m in love with.
  • In formal English the preposition may come at the beginning of the relative clause, before the relative pronoun.
I found the keys for which I was looking.

That´s the woman with whom I´m in love.
Note: We cannot put a preposition before that or who

More examples:
  • listen to
The music is good. Julie listens to the music.
→ The music (which / that) Julie listens to is good.
  • work with
My brother met a woman. I used to work with the woman.
→ My brother met a woman (who / that) I used to work with.
  • go to
The country is very hot. He went to the country.
→ The country (which / that) he went to is very hot.
  • come from
I visited the city. John comes from the city.
→ I visited the city (that / which) John comes from.
  • apply for
The job is well paid. She applied for the job.
→ The job (which / that) she applied for is well paid

  • They are always followed by an infinitive without "to" (e.i. the bare infinitive.)
  • They are used to indicate modality allow speakers to express certainty, possibility, willingness, obligation, necessity, ability.

Modal verbs are used to express functions such as:
  1. Permission

  3. Obligation
  4. Prohibition
  5. Lack of necessity

Reporting Verbs

General information
There is a number of specific reporting verbs which can be used instead of say / tell / ask. These verbs tell us something about the speaker's intention and are a more exact way of reporting what someone says. These verbs give us the meaning of the original words without actually using them all.
For example:
"Honestly, I won't be late, believe me"    He promised not to be late.
Let's revise first the most important basic aspects of reported speech.

changes in verb tenses

"I'm going home"
He said he was going home

changes in expressions of time

"I'm going home tomorrow"
He said he was going home the following day

changes in personal pronouns and possessive adjectives

"I'm going to my uncle's home tomorrow"
He said he was going to his uncle's home the following day
When you first learn reported speech these are the aspects you need to practise. The verbs you use, therefore, are basic ones like say, tell, reply and ask.

However, if you had to interview someone, for example, and then wrote about what the person said, it would be very boring and repetitive if you used only these verbs. Here are a lot of other verbs you can use to describe or summarise what people say without repeating the same thing over and over again. These verbs give us the meaning of the original words without actually using them all.

The section below shows some of these 'reporting verbs' with their meanings and grammatical structures. You can often use verbs you wouldn't normally associate with reported speech, but if they describe the meaning of the original words then use them!

in spite of / despite / although

in spite of / despite / although

In spite ofdespite and although are all used to show a contrast but there are differences in the structures used with them.

In spite of / despite

After in spite of
 and despite we use a noun or a pronoun.
  • We enjoyed our camping holiday in spite of the rain.
  • Despite the pain in his leg he completed the marathon.
  • Despite having all the necessary qualifications, they didn’t offer me the job.
Remember that the gerund (‘-ing’ form) is the ‘noun’ form of a verb.

The only difference between in spite of and despite is the ‘of’.
  • Despite of the bad weather, there was a large crowd at the match.
Although

After although we use a subject and a verb.
  • We enjoyed our camping holiday although it rained every day.
  • Although he worked very hard, he didn’t manage to pass the exam.
  • The holiday was great although the hotel wasn’t very nice.
We can use in spite of and despite with a subject and verb if we include the expression ‘the fact that’.
  • In spite of the fact that he worked very hard, he didn’t manage to pass the exam.
  • Despite the fact that he worked very hard, he didn’t manage to pass the exam.
Even though

Even though is a slightly stronger form of although.
  • We decided to buy the house even though we didn’t really have enough money.
  • You keep making that stupid noise even though I’ve asked you to stop three times.
Like althougheven though is followed by a subject and a verb.
