Son dos palabras muy parecidas, pero tienen un significado diferente. Si todavía no sabes cómo usar say o tell, te lo explicamos abajo.
Personal object
We usually follow tell with a personal object (the person that we are speaking to). We usually use say without a personal object:
- She told me that she loved Jake.
- She said that she loved John.
- He told everybody that he had to leave.
- He said that he had to leave.
Say «to someone»
With say, we sometimes use «to someone»:
- He said to me that he was tired.
- Tara said to Ram that he had done very well.
- Anthony said to her, «I hope you come soon.»
- «I’d like to sleep,» she said to him quietly.
Direct speech
We can use say with direct speech. We use tell only with direct speech that is an instruction or information:
- Ashley said, «Hello Jake. How are you?»
- «That’s great,» she said.
- He told her: «Open the door quietly.»
- She told me, «I have never been to England.»
We can use say with direct questions, but we cannot use tell:
- She said: «Do you hate me?»
- The policeman said to the prisoner, «Where were you at 8pm?»
