1. Choose an action and a conversational style
An action sentence needs a verb that says what happens. Reading, eating, going, and studying are different actions, so choose the Japanese verb before trying to translate every English word. In polite conversation, 読みます can mean read, reads, or will read. The person and time come from the sentence and situation. Japanese does not add a different ending simply because the reader is one person rather than several people.
The ending ます belongs to the verb. It is not an independent translation of English am, and you do not place です after it. The complete form 読みます already has the polite sentence ending needed here. In the earlier noun lesson, 学生です identified a category. Here, 読みます describes an action. Keeping these two predicate types separate prevents combinations such as 読みますです.
Polite forms are a useful starting choice with a teacher, a new acquaintance, or a service worker. They are one part of interaction, not a guarantee that any request or personal question will be appropriate. Plain forms occur naturally among close friends and inside many larger grammatical constructions. Learn to recognize them without assuming that a dictionary form is a mistake. Today's production target is simply a complete, consistent polite action sentence.
本を読みます。
Hon o yomimasu.
I read books.
日本語を勉強します。
Nihongo o benkyō shimasu.
I study Japanese.
2. Let context distinguish a routine from a plan
The form ending in ます is often called nonpast. That label is more accurate than present because the same form can describe something that will happen later. If you say 明日読みます, tomorrow supplies the future setting. If you say 毎日読みます, every day supplies a repeated routine. There is no extra Japanese word corresponding to will in either of these simple affirmative patterns.
Do not use the English translation alone to infer every aspect of the Japanese action. When someone asks what you are doing at this moment, an action in progress commonly uses a different construction, such as 読んでいます. This lesson does not teach that construction in full. Its role here is to establish a boundary: 読みます does not automatically mean am reading right now merely because both sentences concern the present.
Begin with one clear time expression. 毎日 means every day, and 明日 means tomorrow. Neither takes the time particle に in these ordinary uses. An exact clock time, such as 七時に, behaves differently and receives fuller treatment in the time lesson. You can omit a time expression if the conversation already establishes it. State the time when it resolves an actual uncertainty, rather than adding a redundant English style auxiliary to the verb.
毎日読みます。
Mainichi yomimasu.
I read every day.
明日読みます。
Ashita yomimasu.
I will read tomorrow.
3. Build the polite form of an ichidan verb
Dictionaries normally list 食べる, taberu, rather than 食べます. 食べる belongs to the class often called ichidan, group two, or ru verbs. For this class, remove the final る and attach ます: 食べる becomes 食べます. The remaining 食べ is the stem used in this polite form. It is useful to recognize the stem, but a stem alone is not the complete sentence target.
見る, miru, see or watch, follows the same class pattern and becomes 見ます, mimasu. 起きる, okiru, get up, becomes 起きます, okimasu. The operation stays the same even when the resulting stem is short. You are not adding a new vowel just to make every polite form have the same number of syllables. Preserve the actual stem and add the ending.
The class name ru verb can mislead if you treat it as a spelling test. All ordinary ichidan dictionary forms end in る, but some verbs ending in る belong to another class. Learn a new verb with a reliable class label or a confirmed polite partner. A vocabulary record containing 食べる, 食べます, and eat gives you both recognition and usable production. A rule plus a known class is reliable; a guessed class from the final character alone is not. Keep the meaning on the same vocabulary record so that a correct conjugation still refers to the action you intended. For example, seeing and getting up belong to the same conjugation class, but they are not interchangeable actions. Class membership explains how to form the verb, not what the verb means.
朝ご飯を食べます。
Asagohan o tabemasu.
I eat breakfast.
六時に起きます。
Rokuji ni okimasu.
I get up at six.
4. Change the final sound of a godan verb
読む, yomu, belongs to the class called godan, group one, or u verbs. Its polite stem is 読み, yomi, so the complete form is 読みます. In a beginner romanization rule, the final u vowel changes to i before ます. Apply that description to the final sound of the verb, not to every u written anywhere in the word.
Different final kana have their corresponding forms. 書く becomes 書きます, write; 飲む becomes 飲みます, drink; 話す becomes 話します, speak; and 待つ becomes 待ちます, wait. The conventional romanizations shi and chi can make the pattern look less mechanical than a simple letter replacement. Learning the kana pair す to し and つ to ち keeps the actual Japanese sound sequence visible.
A godan verb can also end in る. 帰る, kaeru, return, becomes 帰ります, kaerimasu, rather than 帰ます. This is why an ending resembling eru is a useful clue but not sufficient proof of class. Compare the confirmed pairs 食べる and 食べます with 帰る and 帰ります. When you cannot remember a class, check the dictionary instead of inventing a polite form. Repeated correct retrieval of a small set is more useful than confidently extending an unreliable shortcut.
水を飲みます。
Mizu o nomimasu.
I drink water.
家に帰ります。
Ie ni kaerimasu.
I return home.
Worked example: say what you drink
Say politely that you drink water, using the godan verb 飲む.
- The dictionary verb 飲む has the polite stem 飲み.
- Attach ます to make 飲みます.
- Place 水 before the object particle を, then put the complete verb at the end.
水を飲みます。 Mizu o nomimasu. I drink water.
5. Learn suru and kuru as complete pairs
Two very common verbs have irregular patterns that beginners should learn directly. する, suru, do, becomes します, shimasu. 来る, kuru, come, becomes 来ます, kimasu. Do not obtain these forms by attaching ます to the untouched dictionary word. Saying するます or くるます does not produce the polite forms needed here.
The kanji in 来る remains visible in 来ます, but its reading changes from ku to ki. This is a useful early reminder that a written kanji is not a fixed sound recording. Learn the whole word form with its reading. In a sentence, the person who comes can be left unspoken when the conversation makes that person clear. The verb form itself does not reveal whether the subject is I, you, or someone else.
Many useful actions combine a noun with する. 勉強する becomes 勉強します, study, and 練習する becomes 練習します, practice. You can often learn these as vocabulary units. When another object is present, do not insert an extra を inside the same action phrase: 日本語を勉強します is the pattern here. The object lesson explains this construction more fully. For now, recognize that the irregular part is する, and preserve the noun that identifies the particular activity.
日本語を練習します。
Nihongo o renshū shimasu.
I practice Japanese.
田中さんが来ます。
Tanaka san ga kimasu.
Tanaka will come.
6. Negate the action and describe frequency
Once you know the complete polite affirmative, form the polite nonpast negative by replacing ます with ません. 読みます becomes 読みません, and 食べます becomes 食べません. The polite stem remains the same. This lets you make a useful negative before learning the separate plain negative patterns used in other contexts.
A negative needs the same attention to meaning as an affirmative. コーヒーを飲みません can describe a habit of not drinking coffee or a decision not to drink it in the relevant situation. The surrounding time words and question determine the intended interpretation. It does not necessarily mean the speaker has never drunk coffee in their lifetime. Avoid adding a stronger claim than the Japanese sentence supports.
Frequency expressions make a routine more precise. よく commonly means often, ときどき means sometimes, and あまり with a negative means not very much or not very often. Thus あまり飲みません is not equivalent to always drink. Keep the negative ending visible when practicing that combination. A useful exchange can contrast two ordinary habits without classifying one as superior: one person often drinks tea, while another does not drink coffee very often. Your task is to report the frequency accurately, not to invent a reason for it.
コーヒーを飲みません。
Kōhī o nomimasen.
I do not drink coffee.
あまりテレビを見ません。
Amari terebi o mimasen.
I do not watch television very often.
Guided example: deny tomorrow’s action
You will not eat breakfast tomorrow. Build a polite sentence from 明日, 朝ご飯, and 食べる.
- Use the confirmed ichidan stem 食べ.
- A polite negative needs ません, giving 食べません.
- Mark breakfast with を. The ordinary time word 明日 stays without に.
Compare your reasoning
明日、朝ご飯を食べません。 Ashita, asagohan o tabemasen. I will not eat breakfast tomorrow.
7. Ask about an action and answer the actual question
Place か after the complete polite verb to ask a basic question: 読みますか. The verb does not move to the front, and Japanese does not require an extra equivalent of English do. A question can include an object or time expression, but those words retain their normal relationship to the verb. 明日読みますか asks about reading tomorrow.
When the action is already clear, a short reply can repeat only the verb. はい、読みます confirms it, while いいえ、読みません denies it. A reply ending in です alone would not supply the matching action predicate. You can also answer a question about what you read by naming the object in a complete sentence, such as 本を読みます. The object particle remains attached to the object.
Build a short exchange before trying the choices below. First establish one routine, then ask the other person about the same activity, and finally give a truthful affirmative or negative response. Keep each turn focused on the information the previous turn requested. A place such as 図書館で can add where reading happens, but location marking is a separate decision from verb conjugation. If a sentence fails, check the verb class, ending, and intended time one at a time rather than replacing the whole message at random.
毎日読みますか。
Mainichi yomimasu ka.
Do you read every day?
はい、読みます。
Hai, yomimasu.
Yes, I do.
Notice the difference
Common mistakes
Keep dictionary and polite forms separate
Instead of食べるます
For this meaning食べます
For this ichidan verb, remove る before adding ます.
Remember the class of return
Instead of帰ます
For this meaning帰ります
帰る is godan. The polite stem is 帰り even though the dictionary reading ends in eru.
Do not add a second polite ending
Instead of読みますです
For this meaning読みます
The complete verb already carries the polite ending.
Use the irregular coming form
Instead ofくるます
For this meaning来ます
来る becomes 来ます, read kimasu. Learn the pair directly.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
Describe a daily reading habit politely. Use every day and book.
Compare with a model
毎日本を読みます。 (Mainichi hon o yomimasu.)
I read books every day.
読む is godan, so the polite form is 読みます. 毎日 establishes the routine, and 本を identifies what you read. The sentence does not specify a different book count each day.
- Preserve 読み.
- Keep を after 本.
- Do not put に after 毎日.
Your turn 2
Ask politely whether your conversation partner studies Japanese, then prepare a negative reply.
Compare with a model
日本語を勉強しますか。いいえ、勉強しません。 (Nihongo o benkyō shimasu ka. Iie, benkyō shimasen.)
Do you study Japanese? No, I do not.
The noun plus する action uses します and しません. The reply can omit 日本語を because the question established the object.
- Use しますか in the question.
- Use しません in the negative.
- Do not add です after either verb.

- Every polite nonpast verb means an action is happening this second
- The polite nonpast alone does not automatically express an action in progress
Check the answer
Answer: The polite nonpast alone does not automatically express an action in progress
Every polite nonpast verb means an action is happening this second: Nonpast forms also describe habits and future plans.
The polite nonpast alone does not automatically express an action in progress: The ongoing action construction is separate, such as 読んでいます.
