Say vs Tell: The Simple Rule and Common Email Mistakes

"Say" and "tell" can look like two words for the same idea, but English uses them differently, and the split follows a clear rule about who you mention. Most mistakes, such as "He said me the deadline" or "She told that the meeting moved," come from breaking that one rule.

1. The core rule

The Cambridge Dictionary sums it up:

• Tell is always followed by the person who receives the information or instruction.
• Say is never followed by the person.

If you want to mention the person with say, Cambridge explains that you add to: "And then she said to me, 'I'm your cousin.'"

2. What each verb focuses on

Cambridge describes a difference in focus as well:

• Say focuses on the words someone said.
• Tell focuses more on the content or message.

That is why say is the verb for direct quotes. Cambridge's examples: "'Hello,' she said," not "'Hello,' she told." And "He said, 'I'm not paying £50 for that.'"

In emails, you will mostly report content rather than quote exact words, so both verbs work. Just follow the person rule:

• "The client said (that) the budget was approved."
• "The client told us (that) the budget was approved."

3. Tell without a person: fixed phrases

Cambridge notes a group of phrases where tell appears without a person: tell the truth, tell a lie, tell a joke, tell a story. "You should never tell a lie," not "say a lie."

These phrases are fixed, so learn them as units.

4. Reporting instructions: tell + person + to

When you report a request or instruction, Cambridge says to use tell + person + to-infinitive:

• "They told us to come back the next day." Not: "They said us to come..."
• "They told her to wait till the doctor arrived."

This pattern is very common at work:

• "The IT team told us to restart the laptops."
• "The manager told me to send the report by noon."

Cambridge adds that in informal speaking, people sometimes use say + to-infinitive for a command: "He said to leave it till tomorrow." The word-choice page gives a similar example: "Jim said to meet him here." Notice that even here, no person follows said. In written work email, tell + person + to is the clearer choice.

5. A two-question check

Before you choose, ask:

1. Am I naming the person who heard it right after the verb? If yes, use tell (told me, told the team). If you want say, add to: said to me.
2. Am I quoting exact words? If yes, use say.

6. Before and after

Before: As I said you in the last email, the price includes shipping. After: As I told you in the last email, the price includes shipping. Or: As I said in the last email, the price includes shipping. Why: Say cannot be followed directly by the person.

Before: The vendor told that the parts will arrive on Monday. After: The vendor said that the parts will arrive on Monday. Or: The vendor told us that the parts will arrive on Monday. Why: Tell needs the person after it. Cambridge's example: "She said she would wait for us outside," not "She told she would wait."

Before: Could you say me when the contract is ready? After: Could you tell me when the contract is ready? Why: You are naming the person, so tell.

Before: The director said us to prepare a short summary. After: The director told us to prepare a short summary. Why: Reported instructions use tell + person + to.

Before: He said to me about the change in schedule. After: He told me about the change in schedule. Why: Cambridge's pattern "Simon told me about his new job" shows that tell goes with about to report a topic.
