What's a reduced relative clause?

Reduced relative clauses Look at the following sentences: I can't find my notebook containing all my addresses. She has never met the lecturer leading today's seminar. The tall man standing by the bar is my uncle. The newspaper first reporting the incident is being sued. This is usually referred to as a reduced relative clause and can only be applied to subject relative clauses not object relative clauses. The most obvious feature of this type of reduced clause is that the relative pronoun is left out and the verb following the noun always ends in -ing. The second, but perhaps not quite so obvious feature is that the tense of the verb in the original relative clause is not taken into account. Note how the verb tenses varied in the original sentences: I can't find my notebook that contains all my addresses. (Present Simple) She has never met the lecturer who is leading today's seminar. (Present Continuous) The tall man who was standing by the bar is my uncle. (Past Continuous) The newspaper which first reported the incident is being sued. (Past Simple)
