What is the proper way to speak in the present tense?


Today I'm going to school.

今日、学校に いく。  
今日、学校に いって。  
今日、学校に いって いる。

I know last phrase is right, but his meaning is expressing a present in action
in that moment. How can i express a more neutral present? I have seen examples
of use of both the first and second cases, but I have been told that the first
is not a good example, since it is a present future, non past, that is used in
specific cases that are not what I am looking for.




"I'm going to school" is an ambiguous English sentence; it can mean either "I
will go to school (in the near future)" or "I am on the way to school (now)".
See [Present continuous for future
arrangements](https://www.ef.com/wwen/english-resources/english-
grammar/present-continuous-future-arrangements/). When the original sentence
is already ambiguous, it's usually impossible to find a single Japanese
translation that is equally ambiguous and covers both meanings.

If you mean "I will go to school (in the near future)", the correct Japanese
sentence for it is 今日は学校に行く. If you mean "I am on the way to school (now)",
the correct sentence is 今学校に行っている.

今日学校にいって is a request ("Go to school today!") rather than a description.
