Indicates the direction of movement. Pronounced 'e' when used as a particle. Often interchangeable with に for destination, but へ emphasizes the direction/journey rather than the arrival point.
Common mistakes
Thinking へ and に are always interchangeable (へ cannot mark time or indirect objects)
Pronouncing へ as 'he' instead of 'e' when used as a particle
Marks the grammatical subject, especially when introducing new information or answering 'who/what' questions. Also used with adjectives of desire (〜たい), ability (できる), and existence (ある/いる).
Common mistakes
Using は when が is needed for new information or emphasis
Placed at the end of a sentence to form a question (これは本ですか). Also used between nouns to mean 'or' (コーヒーかお茶). In casual speech, か can be replaced by rising intonation.
Common mistakes
Forgetting か at the end of polite questions
Confusing か (or) between choices with と (and) between items
Marks destination of movement (学校に行く), specific time (7時に起きる), location of existence (部屋にいる), and indirect object or recipient (友達にあげる). One of the most versatile particles.
Common mistakes
Confusing に (existence location) with で (action location)
Using に with relative time words like 今日 or 昨日 where no particle is needed
Connects two nouns to show possession (私の本), affiliation (大学の学生), material/category (日本語の本), or acts as a nominalizer turning verbs/clauses into noun phrases (読むのが好き).
Common mistakes
Overusing の where a different particle or no particle is needed
Lists nouns exhaustively (AとB means A and B, nothing else) or marks a companion for doing something together (友達と行く). Also used for quoting (〜と言う), though quoting is less common at N5.
Common mistakes
Confusing と (exhaustive listing) with や (non-exhaustive listing)
Using と to list more than a few items where や would be more natural
Marks the topic of the sentence — what the speaker is talking about. Often contrasts with が which marks the grammatical subject. は introduces known or contextual information.
Common mistakes
Confusing は (topic) with が (subject/new information)
Overusing は when が is needed for emphasis or new information
Marks the direct object of an action verb — the thing being acted upon. Also used with movement verbs to indicate the place passed through or departed from (e.g., 道を歩く, 家を出る).
Common mistakes
Confusing を with が when the verb takes a direct object
Using を with adjectives or existence verbs where が is correct
Lists nouns non-exhaustively, implying there are more items not mentioned. Often followed by など (etc.). Unlike と which lists everything, や suggests 'things like A and B (among others).'
Common mistakes
Confusing や (non-exhaustive) with と (exhaustive listing)
Using や to connect verbs or adjectives (や only connects nouns)
