Which, who and that are used most often.

The relative adverbs where, when and why are sometimes used instead of a relative pronoun.

Common grammar mistakes

Mistake 1: Forgetting relative pronouns

Mistake 2: Joining two sentences with a comma instead of using a relative pronoun.

Ex: There are many aspects to this problem, one of them is money.Ex: There are many aspects to this problem, one of which is money.

Mistake 3: Forgetting that the relative pronoun replaces the object of the relative clause.

Be carefulSometimes you can simplify a sentence by not using a relative clause!

Participle clauses

With an active verb we use a present participle.

When the active verb is progressive we leave out the relative pronoun and the verb to be.

Active verb: The woman who is sitting next to the door has been looking at you. Do you know her?

With a passive verb we use a past participle and leave out the relative pronoun and the verb to be.

Passive verb: The article which was published in yesterday’s Times could be useful.

Relative clauses with a to-infinitiveLook at this structure with the to-infinitive.

next and last; only; and superlatives, e.g. youngest, most famous.

Prepositions in relative clausesIn formal English, a preposition can be used at the beginning of the relative clause, before which or whom.

Ex1: Electronics is a subject about which I know very little.

Ex2: The people with whom he worked have all been arrested.

Ex3: They collected the sap from the sugar maple trees, from which maple syrup is produced.

Note: We cannot put a preposition before that or who.

Sentential relative clauses

This type of clause does not modify a noun but refers to the whole sentence.
