Both say and tell report speech, so they often appear in the same kinds of conversations. Learners confuse them because each can introduce words spoken by someone else, but the listener is positioned differently in the sentence. The main choice depends on whether the person receiving the information is named directly or whether the focus is on the words themselves. For a broader view of related reporting verbs, compare Direct Speech and Indirect Speech.

Tell normally takes a person as its indirect object, so it follows the pattern tell someone something. It is the natural choice when the listener is named directly, as in requests, instructions, stories, secrets, commands, and news. Tell is therefore more personal and more recipient focused than say. It also appears in fixed expressions such as tell the truth, and it often works well when the speaker wants the message to feel directed at one person. For a related comparison of speech verbs, see Say vs Speak.

Idea	Example
Tell names the listener directly and follows tell someone something.	She told me the news.
Tell is common with instructions and directions.	He told us how to get there.
Tell is common with secrets and private information.	She told him a secret.
Tell is common with stories and reports.	Grandpa told us a story.
Tell is used in fixed expressions such as tell the truth.	Please tell the truth.

Say normally reports the words or utterance itself, so it often appears with quoted speech or with a content clause. It is the better choice when the focus is on what was said rather than on the person receiving it. When a recipient is named, say usually needs to be followed by to, as in say something to someone. In direct quotation, say is the standard verb because the reported words are presented exactly as spoken. In speech reporting, Direct Speech and Indirect Speech show the two most common patterns.

Idea	Example
Say introduces quoted speech.	She said, I'm tired.
Say reports words or content.	He said that he was late.
Say uses to before the listener.	She said hello to me.
Say can report a short utterance without naming the listener.	They said nothing.
Say focuses on the message more than the listener.	He said the meeting was cancelled.

Some sentences can work with either verb, but the focus changes. He said that he was leaving centers on the content of the statement, while He told me that he was leaving highlights the listener who received it. In informal speech, to may be dropped after say when the recipient is obvious, but the fuller pattern with to is the safest general form. Native speakers may also choose one verb over the other for rhythm, emphasis, or fixed phrasing, so usage is guided by pattern as well as meaning. The key test is simple: if the listener must be named directly, use tell; if the message is being reported, use say or say to.

Idea	Example
Said that emphasizes the statement itself.	He said that the train was late.
Told me that emphasizes the listener.	He told me that the train was late.
Say can take to when the listener is named.	She said to him that she agreed.
Choice can vary for emphasis or rhythm.	He said it quietly.
If the listener is required, tell is preferred.	Tell Anna the answer.

Say and tell both report speech, but they organize the sentence differently. Tell is ditransitive and normally takes a person directly, while say is more about the words and usually takes to when a recipient is mentioned. Quote speech with say, name a listener directly with tell, and use the simpler decision rule of direct recipient for tell and message focus for say. Reliable use comes from noticing whether the sentence points first to the listener or first to the utterance.
