Ichidan is a category of Japanese verbs that are characterized by their simple conjugation patterns. These verbs typically end in the syllable "ru" in their dictionary form, making them easier to conjugate compared to other verb types. For example, the verb taberu (to eat) is an Ichidan verb. Ichidan verbs follow a consistent pattern when changing forms, such as for tense or politeness. To conjugate an Ichidan verb, you simply drop the "ru" ending and add the appropriate suffix. This straightforward method makes Ichidan verbs popular among learners of the Japanese language.
