Unit 9b Book

When completing the grammar tasks in the unit, maybe you noticed an interesting fact: there was never a comma before a relative pronoun used in relative clauses in definitions. This may seem a bit weird particularly to Czech students, as there is always a comma used with relative clauses in the Czech language. In English, however, some relative clauses have commas, but some have not, depending on their type. As definitions use defining relative clauses, i.e. the relative clause is important for the meaning of the whole definition/sentence, it cannot be omitted and therefore, there are no commas. Read more about relative clauses in this document. You are not only going to read about commas used with relative clauses, but also have the opportunity to revise the rules of the use of the relative pronouns. After going through the grammar overview, practise the relative pronouns here and here. Then practise the use of commas in this task.
