Verb Forms Japanese Grammar Lessons

The dictionary form is the plain, basic form of a Japanese verb. It expresses present or future actions in casual speech and is the form you will find when looking up verbs in a dictionary. It also serves as an essential building block that connects directly to nouns and many other beginner grammar patterns.

The ます form (ます形) is the standard polite verb conjugation in Japanese. It is used at the end of main sentences to express daily habits, objective facts, and future actions. Mastering this form is essential because it sets a respectful, professional tone for speaking with acquaintances, coworkers, and strangers.

The Japanese て形 (te-form) is an essential verb conjugation that acts as a connector. It allows you to link multiple actions together in chronological order, showing exactly how events unfold. Beyond connecting sentences, it serves as the grammatical foundation for many important everyday patterns.

The た形 (ta-form) is the casual past tense form of Japanese verbs. It is used in relaxed conversations with friends or family to talk about completed actions or events that happened in the past. Beyond casual speech, the ta-form is a crucial building block used to modify nouns and connect with many other essential grammar structures.

The ない form is the plain, casual negative form of Japanese verbs. It is used to state that an action does not happen or will not happen in casual conversations with friends and family. Beyond casual speech, the ない form is an essential building block used to modify nouns and create important grammar patterns like negative requests and obligations.

The verb ending ます is the standard polite way to express actions in Japanese. It acts as the non-past tense, meaning you can use it to talk about present habits, daily routines, general facts, or things you will do in the future. By adding ます to the end of a verb, you show respect to the person you are speaking with, making it the safest and most common verb form to use in everyday life.

The ending ～ません attaches to verbs to form polite negative sentences. It is used to state that you do not do a habitual action, will not do a future action, or that a certain state (like understanding or possession) is not true. This form is standard polite Japanese, making it appropriate for daily use with colleagues, acquaintances, and strangers.

～ました is the polite past tense ending for Japanese verbs. It replaces the present/future polite ending ～ます to state that an action was completed or that an event occurred in the past. This is the standard polite form used in everyday communication with acquaintances, colleagues, and strangers.

The ending ませんでした (masendeshita) is the standard polite form for past negative actions in Japanese. You will use it to state that you did not do something, or to explain that an event did not happen in the past. It is an essential beginner form suitable for everyday polite conversations with coworkers, strangers, and acquaintances.

The verb ending ～ている is one of the most important patterns in Japanese, used to describe an action that is currently happening or a state that remains after a change. Because its meaning depends on the type of verb it attaches to, it translates to "is doing" for ongoing actions and "is in a state of" for resulting conditions. It is also the standard way to talk about occupations, long-term habits, and personal states like knowing or living somewhere.

The Japanese て (te) form is a versatile verb ending used to connect multiple actions in a single sentence. It establishes a natural chronological sequence, allowing you to say that you did one thing and then did another. By using this form, the sentence flows smoothly while leaving the tense and politeness level entirely to the final verb.

The 〜たり〜たりする pattern is used to list a few representative actions as examples, without implying an exhaustive list. Unlike the te-form, which connects actions in a strict chronological sequence, this pattern focuses on the actions themselves regardless of their order. The pattern must always end with a form of する, which determines the tense and politeness level of the entire sentence.

The Japanese pattern ～たことがある is used to talk about your past life experiences. It roughly translates to "have done" or "have experienced" doing something in the past. Unlike the simple past tense which states a factual event, this pattern emphasizes that the action is part of your personal history.

The Japanese pattern ～ないで connects two actions to show that the main action is done while skipping the first action. It is primarily used to express doing something 'without' an expected accompanying action or choosing to do one action 'instead of' another. The tense of the sentence is marked only on the final verb, while the ～ないで phrase remains unchanged regardless of when the event happened.

The ～られる suffix attaches to ichidan verbs and the irregular verb 来る to form passive, potential, and honorific expressions. Because these different functions share the exact same visible form, you must rely on context and particles to understand the intended meaning. In spoken Japanese, the potential form often drops the ら to become ～れる, helping to distinguish it from the passive and honorific uses.

The causative form (～させる) is a Japanese verb conjugation used to express that someone makes or lets someone else do an action. It covers both coercion (forcing someone to do something) and permission (allowing someone to do something), depending entirely on context. Once conjugated, the causative form functions like a standard ichidan verb.

The causative-passive form expresses being forced, coerced, or obligated to do something against your will by someone else. It combines the causative and passive structures to emphasize the speaker's sense of annoyance, burden, or lack of choice. It can also be used to describe when a moving experience naturally causes you to think or feel a certain way.

～てしまう is an auxiliary verb attached to the て-form of a main verb. It is widely used in daily Japanese to emphasize that an action was carried out completely to the end, or to express that something happened accidentally with a sense of regret. In casual spoken Japanese, it frequently contracts to shorter forms like ～ちゃう and ～じゃう, making it an essential pattern for natural conversation.

The Japanese verb ending ～ておく is used to express doing an action in advance as a preparation for the future, or leaving a situation exactly as it is. It can also describe a temporary measure taken for the time being, often functioning as a practical step for immediate convenience. You will encounter this grammar point frequently in JLPT N4 materials and everyday conversations, where it is often contracted to ～とく or ～どく in casual speech.

The pattern ～てみる expresses doing an action as a trial, test, or experiment. It is used when you want to experience something new, check the outcome of a situation, or encourage someone else to give it a try. The auxiliary verb みる is usually written in hiragana and conjugates like a standard ichidan verb.

The Japanese pattern ～ていく combines a verb in its te-form with the auxiliary verb いく (to go). It expresses physical movement away from your current location, or describes an action that you do before leaving a place. In a broader sense, it also describes a state, action, or change that begins now and will continue forward into the future.

The auxiliary verb pattern ～てくる describes an action, change, or state that moves toward the speaker or the present moment. It is used for physical movement coming closer, for gradual changes that have developed from the past up to now, and for actions where someone goes somewhere to do something and returns. By attaching くる to the te-form of a verb, you shift the perspective to focus on the arrival or completion of the action at your current location or time.

The ～よう ending is the casual volitional form used to make invitations or suggest doing something together with close friends and family. It is also frequently used to express your own personal intentions or to talk to yourself about what you are going to do next. This specific ～よう ending is used strictly for ichidan verbs and irregular verbs, while godan verbs use a different ending.

The ～おう ending is the casual volitional form applied exclusively to godan verbs. It is the casual counterpart to the polite ～ましょう and is widely used with friends and family to mean 'let's' or to express strong personal resolve. Learners encounter this form frequently in daily conversation, anime, and manga when characters make spontaneous decisions or invite others to join an activity.

The imperative form (命令形) is the direct, forceful command form of Japanese verbs used to strictly order someone to do something. Because it is highly blunt and can sound aggressive, it is usually reserved for emergencies, cheering at sports events, or quoting orders in reported speech. Learners should be careful to use polite request forms like ～てください in everyday situations instead.

The suffix ～始める, meaning “hajimeru,” attaches to the pre-ます form of the verb to show that an action or process has started. It is commonly used for continuous actions, new habits, or natural processes that take time to unfold. Because 始める functions as a regular ichidan verb, you can easily conjugate the combined word to show past tense, negative forms, or polite speech.

The te-form (～て) is used to connect multiple clauses in a single Japanese sentence. It can link sequential actions, combine descriptions using i-adjectives (～くて), or express a cause that leads to a natural consequence or emotion. The tense of the entire sentence is determined only by the final verb or adjective.

The suffix ～にくい attaches to a verb pre-ます form to show that an action is physically or objectively difficult to perform. It creates a new word that functions exactly like an i-adjective, meaning it can conjugate for tense and directly modify nouns. This pattern focuses on the inherent difficulty of the object or task, not on emotional reluctance.

The pattern ～を～にまかせる is used when you entrust a task, responsibility, or decision to someone else. It implies giving up personal control over the situation and trusting the other party's judgment or ability. You can also use it with abstract concepts, like leaving an outcome entirely up to luck or fate.

The N2 grammar point ～にあたる means 'to correspond to,' 'to be equivalent to,' or 'to fall under.' It is used to explain how something maps to a specific category, role, or unit in a different system. This formal expression is commonly found in definitions, translations, and discussions about rules or relationships.

The pattern ～ないで済む expresses that a situation was resolved without needing to perform a certain action. It usually carries a positive feeling of relief because a troublesome, painful, or costly task was successfully avoided. You will frequently hear it used in the past tense to talk about an issue that is already settled.

The Japanese suffix ～得る (eru/uru) is used to state that an event or situation is logically or objectively possible. It attaches to the part of the verb before ます and is primarily used in formal, written, or news contexts. Note that it is not used to describe personal physical abilities or learned skills.

The Japanese verb ending ～得ない is a formal expression used to state that something is objectively or fundamentally impossible. It attaches to the pre-ます form of the verb to indicate that there is zero potential or possibility for an event to occur. This ending is strictly for objective situations and cannot be used to describe a lack of personal ability or temporary circumstances.

The Japanese grammar pattern ようがない expresses that there is no method or means available to perform an action, rendering it completely impossible. It attaches to the pre-ます form of verbs to emphasize a sense of helplessness, showing that an attempt would be futile even if one wanted to try. In formal contexts or when speaking to superiors, the polite form ようがありません is used.

The Japanese suffix ～がたい attaches to the pre-ます form of verbs to express that an action is emotionally or psychologically difficult to do. It acts like an i-adjective and is primarily used in formal or written contexts with verbs related to mental processes, perception, or interpersonal relations. Use it when something is nearly impossible to believe, accept, or forgive based on your strong internal feelings.

The Japanese verb suffix ～きる expresses that an action is carried out to the very end, leaving absolutely nothing behind. It is often used when consuming a resource entirely, reaching the extreme limit of a physical or mental state, or declaring something with total conviction. You will frequently hear it in its potential form, ～きれる, meaning “able to finish,”, and its negative potential form, ～きれない, meaning “unable to finish,”.

The verb suffix ～かける attaches to the verb pre-ます form to show that an action was started but left unfinished, or that an event almost happened but ultimately did not. When paired with verbs that have a clear duration, like eating or reading, it describes a halfway-completed state. When paired with instantaneous verbs, like falling or forgetting, it shows that the action reached the absolute threshold of happening before being stopped.

自動詞と他動詞 are paired verb types that describe the same kind of change from two angles: something happens by itself, or someone makes it happen. At N4 you learn to choose the matching member of common pairs such as 開く・開ける and 始まる・始める, and to mark the undergoer with が or the object with を. Particle choice follows the active verb: An intransitive clause centers the thing that changes, while a transitive clause names an agent acting on something.

volitional verb names verbs whose core action can be controlled by the will of the person who does it, such as choosing to go, study, sit, or open a window. This N4 enrichment label is meaning-based, not a new conjugation family like godan verbs or ichidan verbs, and it helps you judge which verbs naturally take intention, desire, invitation, and request frames. Keep it separate from non-volitional verb and from transitive versus intransitive pairs: Controllability is about will, not about whether an object is marked with を.

無意志動詞 are verbs for events and states the subject does not control by direct will, such as understanding, existing, becoming, or becoming visible. This N4 enrichment lesson is a classification lens, not a single conjugation ending, and it helps you predict when intention, plan, and direct request patterns sound forced. Learners meet this metalanguage when textbooks separate will-controlled actions from spontaneous, cognitive, sensory, and natural-process predicates.

継続動詞 names continuative verbs: Action or process verbs that can naturally last for a stretch of time, such as 食べる, 読む, 歩く, or 勉強する. With this class, verb て-form + いる / います most often describes an action in progress, not a finished result state. Learners meet this label as N4 enrichment so they can read progressive ている more accurately and keep it separate from nearby types such as 瞬間動詞.

瞬間動詞 are instantaneous (or punctual) verbs: Their core meaning is a near-instant change of state, not a long stretchable process. In the dictionary form they point to the change itself; with ている they often report a result that still holds, such as being open, closed, on, or married. This is a meaning and aspect habit taught at elementary N4 enrichment level, not a special conjugation class like godan verbs or ichidan verbs.

知っている (polite 知っています) expresses a current knowledge state: You already know a person, fact, place, or piece of information. It is built from the godan verb 知る plus ている, and here ている marks a resulting state after coming to know, not an ongoing progressive action of “knowing.” Learners meet this high-frequency pattern early when stating or asking what someone knows, and when contrasting that state with bare 知る “come to know / find out.”

可能形＋を keeps the ordinary object particle を with a potential-form verb when the speaker still frames ability as carrying out an action on something. You meet this pattern at N4 after learning how to form potential verbs, as an enrichment point about particle choice rather than a new conjugation. Both を and が can be grammatical with many transitive potential forms; を is the natural choice when the “can do X to Y” action feel stays strong.

直接受身 is the direct passive: A transitive action is told from the affected side, so the original object becomes the grammatical subject. You form a passive verb, often mark the doer with に when needed, and leave the agent out when the doer is unknown, obvious, or less important. Learners meet this pattern at N4 when describing events, notices, and everyday situations that focus on the person or thing acted upon.

間接受身 is the Japanese passive pattern that presents an event from the viewpoint of a person who is affected, even when that person was not the original direct object of the action. You will meet it when someone reports rain, a crying child, a sudden visit, or something done to a belonging as impact on themselves or another person. It uses the same passive verb forms as other passives, but the subject seat belongs to the affected party, not to a promoted object.

迷惑受身 is the adversity reading of Japanese passive: The subject is the person inconvenienced, harmed, or annoyed by an event. It uses ordinary passive verb endings, often marks the cause or agent with に, and can include intransitive events such as rain as well as transitive loss of belongings. Learners meet this high-frequency N4 enrichment when complaining, explaining disrupted plans, or reading everyday reports of bother and loss.

In a Japanese passive sentence, に after a person, animal, group, or force names the agent—the one who performs the action that the subject undergoes. You meet this pattern early at N4 once you can form passive verbs: The affected person or thing is the subject, and the doer takes に. If the doer is obvious or unimportant, Japanese often drops the に-phrase; this lesson focuses on cases where you want the agent to be explicit.
