Sais vs Says: Which One Is Actually Correct?
If you've ever paused mid-sentence wondering whether to write "sais" or "says," you're dealing with one of the more common mix-ups in English. The confusion makes sense once you understand why it happens — but the answer itself is simple: says is the only correct form. "Sais" isn't a standard English verb at all.
This guide breaks down where each word comes from, why the mistake is so common, and how to make sure you never second-guess yourself again.
The Short Answer
"Says" is the third-person singular present tense of the verb "say." You use it whenever the subject of your sentence is he, she, it, or any singular noun.
- She says the meeting starts at noon.
- The manual says to charge the battery fully first.
- My neighbor says he's moving next month.
"Sais," on the other hand, has no verb function in English whatsoever. The only place it legitimately shows up is as the plural of "sai" — a three-pronged martial arts weapon with origins in Okinawa. Outside of that narrow context, "sais" is simply a spelling error, not an alternate or informal version of "says."
Why Do People Write "Sais" Instead of "Says"?
There isn't just one reason people make this mistake — a handful of factors tend to combine.
The pronunciation doesn't match the spelling. "Says" is pronounced "sez," not "sayz." Because the vowel sound breaks the pattern you'd expect from words like "stays" or "plays," some writers instinctively reach for a spelling that feels closer to what they hear, and "sais" seems to fit that phonetic instinct even though it's wrong.
French verb endings sneak in. French conjugations frequently end in "-ais" — think of forms like "je faisais" (I was doing) or "il allais" isn't even correct in French, but the shape of that ending is familiar to anyone who has studied the language. Bilingual speakers or French learners sometimes import that pattern into English without realizing it.
Autocorrect doesn't always catch it. Because "sais" resembles a legitimate word in other languages, some spellcheckers and keyboards let it slide instead of flagging it as an error the way they would with a nonsense string of letters.
Fast, informal typing. In texting or social media, people write quickly and don't always double-check spelling before hitting send, which lets small mix-ups like this one become habitual over time.
The Grammar Rule Behind "Says"
English adds an "-s" to verbs when the subject is third-person singular. This is basic subject-verb agreement, and it applies far beyond just "say."

So "he say" or "she say" is incorrect — the moment your subject narrows to a single person or thing, the verb needs that added "-s." This is the same rule that turns "run" into "runs," "walk" into "walks," and "eat" into "eats."
What About Questions and Negatives?
Here's a detail that trips people up even after they've mastered the basic rule: when you build a question or a negative sentence using "does" or "doesn't," the main verb drops the "-s" and returns to its base form.
- Incorrect: Does she says anything about the schedule?
- Correct: Does she say anything about the schedule?
- Incorrect: He doesn't says much these days.
- Correct: He doesn't say much these days.
Think of the "-s" as something that can only exist in one place per sentence. Once "does" or "doesn't" is doing the work of showing tense and agreement, "say" goes back to its plain form.
Says vs Said: Don't Mix Your Tenses
Another common slip-up is switching between "says" and "said" in the same sentence or paragraph. Pick a tense and stay consistent.
- Inconsistent: He says he was tired and said he needs a break.
- Consistent: He says he's tired and needs a break.
"Says" belongs to the simple present tense — describing something happening now or generally true. "Said" is simple past, describing something that already happened. Mixing the two mid-thought makes writing feel choppy and confusing for the reader.
Quick Tricks to Lock In the Right Form
If you want a fast way to check yourself before hitting publish or send, try one of these:
- Swap the subject for "she." If "she says" sounds natural in the sentence, you've got the right verb.
- Listen for "sez." If the word sounds like "sez" out loud, it's spelled s-a-y-s — no exceptions.
- Remember there's no "-ais" ending in English verbs. That pattern belongs to French, not English, so if you're tempted to write "sais," that's your cue to stop and reconsider.
- Read your sentence out loud before sending it. Your ear will often catch mismatched tenses or agreement errors that your eyes skim right past.
