Defining clauses Sunday, 11.16.2008, 02:09am (GMT) There are two types of relative clauses in English: those that add extra information (non-defining relative clauses) and those that modify (or define) the subject of the sentence (defining relative clauses). Grammar and Tenses
Defining clausesGrammar and TensesGrammar and Tenses
These clauses define the noun and they identify which thing or person we are referring to. Grammar and Tenses
Things "The present which he bought me is beautiful." Grammar and TensesPeople "The man who has started an English course is from Spain." Using whom Grammar and TensesGrammar and Tenses Whom is used to refer to the object of the verb. The people with whom I was sitting were very noisy. However, it is hardly ever used in spoken English. Instead, "who" is used with the preposition: The people who I was sitting with were very noisy.
Using that Grammar and TensesGrammar and Tenses In spoken English, "that" is often used instead of "which", "whom"or "who". "The present that he bought me is beautiful." "The man that has started an English course is from Spain." Grammar and TensesWhen, where and whose When: Is there another time when (that) I can call you? Where: Can you tell me where I can buy wrapping paper? Whose: (possessive) Have you seen the TV show whose catchphrase is "Deal no deal?" Grammar and TensesOmitting that, who and which If the pronoun ("that", "who", "which") is the object of the verb, it can be omitted. "The company that she works for is based in London." ("That"is an object pronoun.) = "The company she works for is based in London." ("That"can be omitted.) But:
"The company that employs her is based in London." ("That" is a subject pronoun.) The company employs her (the company is the subject). In this case, it is not possible to omit "that". You need the pronoun because it is the subject of the verb. Grammar and TensesNon-defining relative clausesThese clauses add further information. "My students, who are all adults, are learning English to get a better job." "The textbooks, which the students like, have lots of helpful examples." Commas are used to separate the relative clause from the rest of the sentence. "That" cannot be used instead of "who"or "which" in non-defining relative clauses. You can use "some", "none", "all" and "many" with "of which" and "of whom" to add extra information:
