question
usage expressions idioms
Difference of 「なんとかなる」 vs. 「だいじょうぶ」
"なんとか" means "somehow" so "なんとかなる" literally means "it will become (good)
somehow". When you use "なんとかなる", you are not 100% sure about whether you will
be okay or not. There is a hint that you are somehow relying on the nature to
take its course; "Que sera, sera"; whatever will be, will be. Adding "か？", "よ"
or "さ" just changes the statement into a question, an exclamation, an advice
or the like; it does not change the level of your confidence in the statement
much.

"大丈夫" on the other hand is a strong affirmation that everything is okay.
Although it is a set-phrase, we can see how strong an affirmation it is from
the literal meaning of its components - 大 means "big" while 丈夫 means "strong
and durable". It is no where as wishy-washy as "なんとか". When you use "大丈夫", you
mean it.

However, it's worth nothing that both of them sometimes are used together in
the form of "大丈夫だよ。なんとかなる。". Rather than looking at it as self-contracting, I
would say that it is a pattern of conversation, where you give your assurance
first and then give a hint to the other person that you might not want to take
the full responsibility of whether he will really be okay or not later, for
when you don't want to say "It's okay, I myself will make sure you will be
okay".
