Difference between -masu and dictionary form

[Dante17]

Hey. Weird question here and I really should know the answer :L I got to thinking, and what is the difference between the dictionary form of a verb and the masu form?

E.g: Hashiru and hashirimasu

Couldn't they both be used to say "I run everyday " such as

"Watashi wa mainichi hashirimasu"

And then change hashirimasu to Hashiru? Would mean the same thing right?

Sorry for the stupid question, it's just been bugging me for a while.

Sorry about the title typo. Damn autospell.

I thought it was just the politeness level.

Difference between mash form and dictionary form

I thought it was just the politeness level.

That could be the case. I also wonder that if I were indeed to use just the dictionary form that it would need desu instead of masu...

EDIT: Just googled it and now understand that there is an entire casual form that I was unaware of. Seems to answer my question

I don't think so. You may use n desu short for no desu in spoken language to soften or infer reason.
For example.
Doushite tabenai n desu ka. Why don't you eat?
Onaka ga suite inai n desu. Because I'm not hungry.

You can't just add です to a plain form verb. You can pad it with のだ、んだ but it will have slightly different meaning so not the same.

Masu form is much more regular than plain form which is why it is taught in beginner courses. I.e. Past tense is always ました but in plain form it will change depending on verb. 読んだ、帰った、破いた etc.

"-Masu" is attached to verbs, whereas "-desu" is for na-adjectives / nouns. The explanatory "no / n" belongs to nouns, therefeore "-desu" is used for it. "- Desu" is also used for i-adjectives or the negative form / -tai form of verbs, which is treated as an i-adjective. However, this "-desu" is not a copula but a polite suffix that does not have inflections.
