自動詞と他動詞

Japanese verbs are divided into intransitive verbs that use particles like に/へ/が, and transitive verbs that use を

Meaning

Japanese verbs are divided into two categories: intransitive verbs and transitive verbs. Intransitive verbs show an action or state without a direct object and cannot take the を particle; they typically use particles like に, へ, が, or と. Transitive verbs show an action performed on an object and require the を particle to mark the direct object. Many verb pairs share the same kanji but differ in whether they are intransitive or transitive.

Summary

  • Intransitive verbs describe actions or states without a direct object and use particles like に, へ, が, or と instead of を
  • Transitive verbs require a direct object marked by を and describe an action performed on someone or something
  • Verbs ending in す are always transitive; intransitive verb pairs often end in える or える conjugations, while potential and ability verbs (見える, できる) are typically intransitive
