意味

Describes acquiring information or knowledge from an external source. The basic form 知る indicates the moment of learning something new, while the te-form 知っている expresses the resulting state of knowing.

The crucial distinction with 知る is between the momentary act (知る) and the resulting state (知っている). When someone asks if you know something, the correct answer is 知っています (I know) or 知りません (I don't know) — not 知っていません. The negative non-past 知らない means 'I don't know' as a state, functioning as the negative counterpart of 知っている. 知る differs from 分かる in that 知る is about possessing factual information (names, facts, news), while 分かる is about comprehending or grasping meaning. The object of knowledge is typically marked with を when emphasising the act of learning, or が in some expressions.

関連フレーズ

ある (existence of inanimate things) Indicates that an inanimate object exists or is located somewhere. It is the counterpart of いる, which is used for animate beings. ある is one of the most fundamental verbs in Japanese and is essential for describing the presence or location of things. いる (existence of animate things) Indicates that an animate being — a person, animal, or other living creature — exists or is located somewhere. It is the animate counterpart of ある and is one of the first verbs learners must master for describing who or what is present. いる (progressive / ongoing state) Used after the て-form of a verb to indicate that an action is currently in progress or that a state resulting from a past action continues. This is the most common way to express the English present progressive ('is doing') in Japanese. する (causing a state or action) The verb する is used to indicate that someone or something causes a state or action to take place. It is the most basic and widely used verb in Japanese, functioning as 'to do' and forming the basis of hundreds of compound verbs with nouns. 分かる・わかる (understand) Expresses that something becomes clear, understandable, or known to someone spontaneously. The thing understood is marked with が, and the person who understands is marked with に or は. It describes a natural, involuntary process of comprehension. 好きだ・すきだ (like) A na-adjective that expresses liking or fondness for something or someone. The liked object is marked with が, and the person who likes is marked with は. It functions as an adjective describing a state of preference, not a verb. ある (resultant state) Used after the て-form of a transitive verb to indicate that something has been done and the resulting state remains. This pattern emphasises the current condition that resulted from a completed action, rather than the action itself. する (cost or duration) する is used to express how much something costs or how long something takes. The amount or duration is typically marked with が, and する indicates the price or time required. This is an idiomatic use distinct from the action-performing する.
