When you make Japanese sentence, normally it will not finish with 名詞（めいし）like [これ(N1=④代名詞)は　くるま(N2=①普通名詞)　（KoReWa KuRuMa/This is a car）].

We need to add [です。 or だ。or である。] after N2.

[です。] is making polite sentence, so we use [です。] for daily conversations.
※[だ。][である。] generally use for writing.

(WaTaShi Wa AMeRiKa JiN DeSu= I am American)

(N1) is [わたし=I]　(N2) is [アメリカ人=American]
= ((N2)is explain the attributes and situation of (N1))

You can introduce your name with [わたしは　(your name)です。]

（KyoU Wa ShiGaTsu JuUIChiNiChi DeSu=Today is 11th of April）

(N1) is [きょう=Today] (N2) is [４がつ１１にち=11th of April]
=((N1) and (N2) is match ※[N1=N2]=11th of April is Today also work)

（KaRe Wa GaKuSeI DeSu＝He is a student）

（N1）is [かれ=He]（N2）is [がくせい=Student]
=((N2)is explain the attributes and situation of (N1))
