Difference word endings

What is the difference between al the endings you see in words like?

  • ru
  • se
  • i
    Does this have something to do with grammar?

WaniKani includes the part of speech in the lesson information. Do you look at that?

ye i see suffix, noun or anything like that.

Great thing you started to notice the pattern, yeah it is related to grammar. At your point it’s advised that you start learning grammar. Of course that doesn’t mean you should stop learning kanji, learn the two simultaneously


Just to answer what I think you wanted to know (and what I know so for):

The vocabulary ending with “u” are verbs, the ones endling with an “i” are usually adjectives and so on.

But don’t just ask here. Grab a book that explains grammar. Or well there are many means to learn grammar. Do whatever fits your learning style and preferences. For me its books.
I started with the Genki books. Which is a language course, including grammar.

When you get your vocab lessons, in the meaning it tells you: “blabla ends with a う sound so you know it’s usually a verb” or something like that, same this with い, it’s usually an adjective, and from what I remember adjectives ending in さ are a precision of that adjective, like with 大きさ which you should remember and 大きい, the first one being size, aka, a precision of big, the second one. (I think)
Then I don’t recall anything else from wanikani, (probably because I’m fairely low level) but start learning grammar on the side, you’re at the right level for that !

Oh and one more thing, if you don’t know the difference between the endings and all that, you probably don’t use Kaniwani, you should look into it depending on what your goals with japanese are, it’s the same thing as WK but gives you the english word, and you need to give it the reading in japanese.

Ye, because this way I can stop guessing and really understand how to read a word and what it means. This way you can also understand sentences better or how to use a word when you want to say something.

1)Like what is the difference between
-nomu, to drink or

  • taberu, to eat
    Why one ends with mu and the other with ru
  1. what grammar can you suggest to practice this?

Definitely don’t go just on rules of thumb. Start into grammar. Any godan verb ending in う will end in い as a noun which will make it look like an adjective (買い、使い、通い etc these are not 形容詞 edit: these are not adjectives) and learning transitive/intransitive patterns will help you to not mistake 上げる for 上がる etc. Some patterns might lead you to wrong conclusions if you go in blind.

Edit: 食べる is an ichidan verb, 飲む is a godan verb, they have different conjugation rules (ie past tense 食べた vs 飲んだ). Most people would recommend Tai Kim, I would recommend imabi, there are a lot of great free grammar resources out there.

Oh man this grammar thing, is like jumping in a big ocean while you cant swim.

Nah, it’s just like learning kanji. Start simple and work your way up. Combined with kanji learning and gradually adding some reading it’ll slowly come together and you’ll go from doggy-paddling in the shallow end to carving the ocean in no time.


Yeah, start with a grammar guide which will help you build up the foundation just like are you are doing here with kanji. Then you can pair it up with something like Bunpro if you want to use an SRS system for recall on grammar points.

That’s what I was thinking
