Here's a breakdown:
Said:
* Past tense: Used when the speaking or writing happened in the past.
* Example: "He said he was going to the store."
Says:
* Present tense: Used when the speaking or writing is happening now, or is a general statement.
* Example: "She says she'll be here soon."
Here are some other things to keep in mind:
* Direct quotes: "Said" is typically used for direct quotes, regardless of the tense.
* Indirect quotes: "Says" can sometimes be used for indirect quotes, especially when the speaker is still present.
Examples:
* Direct quote: "I'm tired," she said.
* Indirect quote: "She says she's tired." (even though she's not currently speaking)
Remember, the key is to match the tense of "said" or "says" to the verb describing the action of speaking.
