How to distinguish one, two and three verbs in Japanese?

According to the flexible use form to distinguish:

One kind, also known as five-segment verbs, is used flexibly in the five segments of the line where the suffix is located, such as line, which is used flexibly as line () line, line and line, and kakikukeko line is distributed under the pseudonym Ka, so

The second category, also called paragraph verbs, can be divided into the previous paragraph and the next paragraph. * * * The same thing is that they all end in る, and the pen names before る are in ぃ or ぇ paragraphs. For example, "Qi" and "Qi" are used flexibly, and changes are all in "Qi".

These three categories are divided into two types, one is called change, and the other is called change. かる has only one word, and さる is a compound verb consisting of する and many words directly added with する.

Grammar:

Verb inflections in Japanese can't reflect the person and the singular and plural. In modern Japanese, all verbs in modern Japanese dictionaries end with some pseudonyms (ぅ, く, ぐ, す, む, つ, ぬ, も, も). From this point of view, the verb "taberu" is like the prototype of the verb "eat" in English, although it is actually the simple present tense, meaning "eat"/"eats" or "will eat". Other forms of modification are "history"
