VERB GROUP IN JAPANESE

Overview - Verb Groupings

Japanese verbs can be classified in several ways.
The two most important classifications in learning Japanese verbs, group belonging and transitive or intransitive, are introduced here.

Classification according to conjugation

Japanese verbs have inflection. They are classified into three groupings according to the way they are conjugated.
Verbs in the same group follow the same rule when making various verb forms (with some exception).

Group 1	:	most i-ending verbs (iki-masu, kaki-masu, ai-masu)
Group 2	:	all e-ending verbs (tabe-masu, ake-masu, de-masu)
		some i-ending verbs (mi-masu, i-masu, kari-masu)
Group 3	:	two verbs; shimasu and kimasu (to come)

Transitive verbs and Intransitive verbs

Japanese transitive and intransitive verbs are written using the same Kanji but are read differently in many cases.

In our materials, they are entered separately; "vt." is used to indicate transitive verb, "vi." for intransitive verb.

ex.	kowashimasu	(vt.)	壊します	Transitive verb
	kowaremasu	(vi.)	壊れます	Intransitive verb

Kodomo wa jitensha o kowashimashita.

My child broke a bicycle.

Jitensha wa kowaremashita.
