です attaches to nouns and adjectives, showing what something IS. ます attaches to verbs, showing what something DOES. They are not two polite versions of the same word — they belong to completely different word groups.
This guide is for N5 learners who keep guessing between です and ます. After reading, you will have a quick test you can use before you speak, plus real examples from ordering food, salon visits, and phone calls.
Quick summary: です goes with nouns and adjectives, ます goes with verbs — the choice is about word type, not politeness level.
| Ask yourself | です case | ます case |
|---|---|---|
| Is it a noun or descriptive word (no action happening)? | 学生です / 静かです | — |
| Is it an action someone does or will do? | — | 食べます / 行きます |
| Could I swap in English “is/am/are”? | Yes → です | No, it’s an action verb → ます |
| Is it a verb + いる/ある chain describing an ongoing result? | — | Stays ます family: 入ってます, 持ってます |

Why English Speakers Mix Up です and ます (It’s Not About “Politeness Level”)
The one-word-for-everything habit from English
In English, “to be” does a lot of jobs. “I am a nurse” names something. “I am tired” describes something.
Because one word covers both jobs, English speakers expect Japanese to work the same way. They look for one all-purpose polite word.
Textbooks often make this worse. They translate です as “is” and ます as “do/does,” but rarely explain why there are two forms at all.
So learners guess that です and ます are just “the polite version,” picked by feel rather than by word type. That guess is the real source of most mistakes.
English already keeps “to be” (is/am/are) separate from action verbs (runs, eats, calls) without thinking about it. です is Japanese’s “to be” family, and ます is Japanese’s action-verb family. You are not learning a new split — just noticing the one you already make in English.
The analogy breaks in one spot. English “to be” also covers location and existence, like “I am at the station.”
Japanese hands that job to います and あります, not です. So if you’re saying where something IS or that something EXISTS, this です anchor stops working.
The 2-Second Test: です or ます?
One question, no grammar terms needed
Right before you speak, ask: “Am I naming or describing what something IS, or saying what someone DOES?” Naming or describing → です. Action → ます.
This test works mid-sentence, before you even finish the thought. Just check what kind of word is about to end the sentence.
If you could swap in an English action verb — runs, eats, calls — it’s ます territory. If you’d use “is/am/are” instead, it’s です territory.
When to Use です: Naming and Describing
です closes sentences with no action in them
です closes sentences built on nouns and adjectives. Nothing is “happening” — something just IS.
Even reactive comments, like praising food or confirming a fact, often end in です. As long as no action is involved, です is the right ending.
Japanese: わあ、この卵焼き、めっちゃ甘いです!
Romaji: Waa, kono tamagoyaki, meccha amai desu!
English: Whoa, this tamagoyaki is really sweet!
Why: い-adjective plus です, no action at all — you’re just reacting to what something IS.
Japanese: 予約は七時からです。
Romaji: Yoyaku wa shichi-ji kara desu.
English: The reservation starts from 7 o’clock.
Why: Noun/time-phrase plus です — nothing is being “done,” it’s a stated fact.
When to Use ます: Actions in Progress or Planned
ます always rides on a verb stem
ます always attaches to a verb stem. It exists because Japanese verbs conjugate for politeness in a way English verbs don’t.
Requests, plans, and offers all end in ます. This is true even when the English translation sounds like a state — “I’ll go” is still 行きます, not a です description.
Japanese: 前髪を少し切ってもらえますか?
Romaji: Maegami o sukoshi kitte moraemasu ka?
English: Could you cut my bangs a little?
Why: An action is being requested (cutting), so it needs a verb plus ます — です can’t substitute here even for extra politeness.
Japanese: 私も今度作ってみます!
Romaji: Watashi mo kondo tsukutte mimasu!
English: I’ll try making it myself next time!
Why: This is something you will DO, so it needs ます; です would sound like you’re just describing a fact instead of committing to an action.
The Gray Zone: When Adjectives Turn Into Actions (and Verbs Sound Like States)
Where the です/ます split gets tricky
Some learners try to fix “extra politeness” by stacking both endings on one sentence. That never works, because a sentence needs only one ending.
ここに座りますです。
ここに座ります。
English speakers often assume stacking two “polite words” adds extra courtesy. It’s the same habit as piling on “please” and “kindly” in English.
Common Mistake: この店員さん、親切ます。 should be この店員さん、親切です。 Learners over-generalize the ~ます pattern from real verbs like 食べます and 行きます, assuming any word plus ます means “polite present tense” without checking if the word is actually an action. If the word describes a quality — kind, quiet, convenient — it needs です, not ます.
There’s also a subtler trap. Adjectives can turn into actions with the ~くする / ~にする pattern, and once they do, they need ます, not です.
Some verb forms, like ~ています, describe ongoing states that feel like です material. But they are still verbs underneath, so they stay in the ます family.
Japanese: うーん、やっぱりもっと短くします。
Romaji: Uun, yappari motto mijikaku shimasu.
English: Hmm, actually, let’s make it shorter.
Why: The adjective 短い turns into an action with します — this ~くする pattern is exactly why learners mistakenly try “adjective + ます” on its own.
Japanese: その日はもう予約が入ってます。
Romaji: Sono hi wa mou yoyaku ga haitte masu.
English: That day already has a reservation booked in.
Why: 入ってます (from 入る + いる) describes a resulting state but is still verb-based underneath, so it stays in the ます family instead of switching to です.
FAQ: です vs ます for N5 Learners
Can I say 食べますです to sound extra polite?
No — that stacks two predicate types on one word, which isn’t real Japanese. Just say 食べます; です never attaches after a ます verb.
Why does 持っています end in ます and not です if it’s describing a state?
持っています is built from the verb 持つ (to hold) plus いる, so grammatically it’s still a verb chain. Even though the meaning (“I have/am holding”) feels like a description, verb-based means ます stays.
Is 元気ですか the same as 元気ますか?
元気ますか isn’t valid Japanese — 元気 is a na-adjective/noun, so it can only pair with です, never ます. Always say 元気ですか.
Quick Quiz: Test Yourself
Try these three questions before checking the answers below.
- Which is correct for a quiet library: 図書館は静かです or 図書館は静かます?
- Do 友達は静かです and 友達が静かにします mean the same thing?
- Fix this sentence: この靴、素敵ます!
1. 図書館は静かです – 静か is a na-adjective describing a state, so it pairs with です. ます only attaches to verb stems, and 静か isn’t a verb.
2. No, they mean different things. – 友達は静かです means “My friend is quiet” (describing their personality/state, です on the adjective). 友達が静かにします means “My friend will be quiet / will make things quiet” (an action, using the ~にする pattern to turn the adjective into something someone DOES, so it takes ます). Same root word, different meaning because one is a description and one is an action.
3. この靴、素敵です! – 素敵 is a na-adjective, not a verb, so it can’t take ます directly — it needs です to complete the sentence.
Summary: です vs ます
- です pairs with nouns and adjectives (what something IS); ます pairs with verbs (what something DOES).
- The 2-second test: about to name or describe something → です; about to state an action → ます.
- Watch for adjectives turned into actions with ~くする/~にする — that’s when ます suddenly shows up attached to adjective-based ideas.
Once this split feels natural, the next step is learning how います and あります handle location and existence — the part where the です/ます anchor stops working completely.
