I don’t understand what this grammar point is supposed to be telling me?

Hey :grinning:

The idea is to help students learn and memorize basic conjugation of る verbs (ichidan verbs), and help them realize the difference with another kind of verbs that end with る (the う verbs with る ending, ごだん verbs with る ending). It is very important.

Lets compare two verbs:
たべる to eat. the いちだん verb
わかる to understand. the ごだん verb with る ending

Polite non-past: たべます・わかります
Polite non-past negative: たべません・わかりません
Polite past: たべました・わかりました
Polite past negative: たべませんでした・わかりませんでした
Short form non-past: たべる・わかる
Short form non-past negative: たべない・わからない
Short form past: たべた・わかった
Short form past negative: たべなかった・わからなかった

As you can see, the conjugations are different. What is more, almost every other conjugation like potential form, て form (with exception of ば form) are also different.

But I agree, the grammar point seems a bit unclear. :bowing_man:

I will do my best to fix that!

My review was:

(Casual) → 借かります

How am I supposed to know if it is the Godan or Ichidan Version casual version?

They both are the same when polite, no ?

I’ve never thought about it before, but is it true that ichidan verbs always end in -iru or -eru?
This vastly simplifies telling apart ichidan and godan verbs, imo. Should be a ‘fun fact’ or something.

#9

It is true that ichidan verbs end in -iru or -eru, however there are exceptions and not all verbs that end in -iru and -eru are ichidan verbs.

For example 切る ‘kiru’ ends in -iru and 減る ‘heru’ ends in -eru, but these are both godan verbs.

I came for this same exact question…

If I don’t know that vocab I am going off the form there and both are the same meaning conjugated form when I looked it up, so how would I be expected to guess correctly here, and/or is it even important in instances like this? Should this example just be accepting either? Or rather change to a different word if it is specifically trying to test ーる verbs?
