You may have heard of RU verbs as class two/type two verbs or as ichidan (いちだん) verbs. All these labels are used to describe Japanese verbs that end in ru (る). I’m going to provide some examples of a couple of verbs that end in ru that are not considered a part of this group. For now, I’m only going to give you the verbs that follow the regular conjugation, so for now, don’t worry about the irregular ones.

Verb in the Infinitive (also known as the dictionary form): taberu (たべる) to eat

Verb in the present indicative tense: tabemasu (たべます)(食べます)

Infinitive: akeru (あける) to open

Present indicative: akemasu (あけます)(開けます)

Infinitive: oshieru (おしえる) to teach

PI: oshiemasu (おしえます)(教えます)

Infinitive: dekiru (できる) to be able

PI: dekimasu (できます)(出来ます)

Infinitive: neru (ねる) to sleep

PI: nemasu (ねます)(寝ます)

Infinitive: okiru (おきる) to get up

PI: okimasu (おきます)(起きます)

If you’re unsure about how to form the present indicative, follow this guide and soon you’ll see there’s nothing to it. 1) Take the ru ending off the infinitive 2) add the masu (ます) to the stem of the verb. Let’s take taberu (たべる) as an example. When you take the ru off of taberu (たべる), you’re left with the stem, tabe (たべ). Then add masu (ます) to the stem and you’ll get tabemasu (たべます). This will work with all the verbs listed above. Try it! Also, I’ve provided the kanji next to the present indicative of the verbs because these verbs will often show up in the kanji as well.
