だ and です godan or ichidan


Can we say, that だ and です are godan verbs with ru-ending, because they are
just simplyfied versions of である and であります?




According to goo 辞書 dictionary.goo.ne.jp, だ and です are simply 助動詞 or じょどうし。
(helping or auxiliary verb)

I like goo 辞書 for the monolingual definitions.

ある is 動ラ五 meaning 動詞 (どうし)、ラ行 (ぎょう)、五段 (ごだん)。

To me, だ and です are not very verb-like.

It might not be useful to classify them.

I hope this helps!
