Verbs(どうし）
Verb is a word to express action such as eat, go and write. In Japanese most verbs end with u sound. If I say more, there are verbs end with ru sound and u sound.
1. verbs end with ru sound.
みる (miru) watch たべる (taberu) eat
きる (kiru) put on くる (kuru) come
こたえる (kotaeru) answer しんじる (sinjiru) believe
2.verbs end with u sound.
いく (iku) go あそぶ (asobu) play
かく (kaku) write うごく (ugoku) move
きく (kiku) listen さく (saku) bloom
I think you don't have to remember what I will say from now but it might be useful if you just know that. Like English there are intransitive verbs (vi) and transitive verbs(vt) in Japanese also. Intransitive verbs don't have objects and express the subject's action itself. Transitive verbs have direct objects and affect the objects.
1.intransitive verbs
example sentence usage
さく (saku) bloom → はなが さく (hanaga saku) flowers bloom.
ほえる (hoeru) bark →いぬが ほえる(inuga hoeru) dogs bark.
2.transitive verbs
みる (miru) watch →わたしは てれびを みる (watashiwa terebio miru) I watch TV.
よむ (yomu) read →わたしは ほんを よむ (watashiwa hono yomu) I read a book.
In Japanese there is also a verb as the same usage as be-verbs. There is no change by the subjects like English.
for example
I am a student. → わたしは がくせい です。(watashiwa gakusei desu)
She is a student. → かのじょは がくせい です。 (kanojowa gakusei desu)
No matter which subjects , in Japanese we use です（desu) for the present tense.
