About る-Verb (Dictionary)
る-Verbs are verbs that have only one possible conjugation pattern. This pattern simply involves the replacement of る with another construction, depending on the tense of the verb (past, negative, etc). This conjugation pattern that only includes る is where the Japanese name Ichidan (一段) 'one-level' comes from.
In these examples, we can see that る is removed from the verb to create the polite ます form. The る form of the verb is often called 'plain form', 'casual form', or 'short form', depending on the source/book.
All る-Verbs end in the kana る, there are no exceptions to this rule.
Caution
While all る-Verbs end in る, not all verbs that end in る are る-Verbs. These verbs can be identified by the る changing, rather than being removed when conjugated.
As the る in 取る becomes り in 取ります, we can determine immediately that it is not a る-Verb, but actually an う-Verb.

In this Topic, we're going to get our first look at Japanese verbs, and learn about two main types. る-Verbs and う-Verbs. Knowing the difference is important, as it affects how they conjugate (change so other words can attach to them).

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.
Fuga
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?
