“They say reported speech is easy“. That’s the title of VOA’s audio on reported speech.
When we want to tell someone what someone else has said, we can do so in two ways. One is to use exactly the same words the speaker used and to use quotation marks. That is called “direct speech”. The other way is to summarise or to talk about what someone has said. This is called “reported speech”.
Have a listen to see if you can remember the rules.
