Grammar, Comparative and general Indirect discourse

In linguistics, speech or indirect discourse is a grammatical mechanism for reporting the content of another utterance without directly quoting it. For example, the English sentence Jill said she was coming is indirect discourse while Jill said "I'm coming" would be direct discourse. In fiction, the "utterance" might amount to an unvoiced thought that passes through a stream of consciousness, as reported by an omniscient narrator. In many languages, indirect discourse is expressed using a content clause or infinitival. When an instance of indirect discourse reports an earlier question, the embedded clause takes the form of an indirect question. In indirect speech, grammatical categories in the embedded clause often differ from those in the utterance it reports. For instance, the example above uses the third person pronoun "she" even though Jill's original utterance used the first person pronoun "I". In some languages, including English, the tense of verbs can also be changed following the sequence of tense. Some languages also have a change of mood. For instance Latin indirect speech uses the infinitive for statements and the subjunctive for questions.
