How to use "なんとかなる" in the context "it's okay, I'll make things okay"?


I want to know how to properly write なんとかなる. I've seen multiple ways:
なんとかなるさ、なんとかなるよ. I saw something somewhere saying that なんとかなるよ was like saying
"everything will be okay" or "I will make it okay". But somewhere else I saw
someone using 大丈夫だよ。なんとかなる as a form of asking and affirming things will be
okay, I'll make sure of it.

I want to know how to say that "everything will be fine, I'll make sure of
it/I will make it happen" and if なんとかなる is okay and how to use it.




In some cases you can use なんとかなる to say 'everything will be fine', but なんとかする
might be better when you want to convey that you are really committed to
improve the situation.

Literally なんとかなる means something like 'the situation will just take its
course; things will go as they go'. It is in 3rd person, more neutral as such,
and does not tell whether the speaker really does something.

For example, if you are talking about a work project that is stuck with some
problem, you would better tell your supervisor なんとかします because なんとかなります would
sound irresponsible or vague.

I think people (like me) tend to use なんとかなる more exactly because it does not
put any responsibility on those who say this :). So the distinction is partly
psychological, and using なんとかなる does not necessarily mean that the speaker
will NOT do anything.

**A note on the endings**

The endings よ or さ do not affect the meaning.

Roughly,

  * よ in 何とかなるよ indicates that the speaker particularly tries to make the listener be aware that it will be okay.
  * 何とかなるさ sounds masculine

If uttered cheerfully, it sounds more optimistic and probably softer than
なんとかなる. A possible English parallel is saying it with emphasis on 'will':
"Things _will_ be fine!"

FYI: なんとかなるわ is a feminine version and なんとかなるわよ is feminine + emphasis same as
よ above.
