This course will first introduce you to relative clauses and how they are used to better define the noun that precedes them. You will learn that they start with relative pronouns such as 'who', 'whose', 'that', 'which', 'where', and 'when'. You will also learn that personal pronouns such as 'I', 'he', 'she', and 'it' are not used in relative clauses. The course will also teach you that prepositions in sentences and in relative clauses are attached to the verbs.

You will then look into the relative pronouns 'that' and 'what'. You will learn that both refer to things and that you use 'that' to refer to what is known, which is basically the noun, and 'what' to refer to what is not known. You will study how to use 'where', 'whom', 'that', and 'why' correctly. The course will also teach you that you should use 'whose' in relative clauses to provide information about what belongs to or relates to other people.

Relative clauses can help you express yourself more accurately, which is really important for personal and career advancement. If you can express exactly what you want to say, you can avoid confusion, make your conversations easier, and sound a lot more like a native English speaker. These are great rewards, so why wait? Check out this free online English course and start learning about relative clauses today.
