What is the exact meaning of はな in the sentence: 「世の中的にはな。」


In order to understand the meaning of this sentence:

> "まぁうん 一応 世の中的にはな。"

I put the complete conversation below:

> Son: 「大人」って何？「大人」ってどういうこと？  
>  Father: 大人？  
>  Son: うん 親父 大人だろ？  
>  Father: まぁうん 一応 世の中的に **はな** 。  
>  Son: いや 真面目に聞いてんだけど。




It's not はな{hana}, but はな{wana}. The は is actually the particle "wa" here.

The part `一応世の中的にはな` should be interpreted with the preceding context, which
makes it `一応世の中的には親父は大人だろう`. The な at the end is a sentence-ending particle,
just like よ or ね.

In casual speech, it's not a problem to put XXXは(the subject) at the end of
the sentence, and in fact, since all parts of a sentence in Japanese are
clearly labeled by particles, in daily speech one could alter the sentence
order however they like, and we do that sometimes in English too.

> Take that book to you, I will. (I will take that book to you)  
>  あの本を上げるよ、俺は。 (俺はあの本を上げるよ)  
>  あの本を上げるよ、君に。（君にあの本を上げるよ）

So, for your conversation, you should interpret the sentences as such:

> 「大人」って 何? (What's an adult?)
>
> 「大人」って どういうこと? (Adult is what kind of thing?)
>
> 大人? (Adult?)
>
> うん 親父 大人だろ? (Yeah, my father should be an adult?)
>
> まぁうん 一応 世の中的にはな。 (Um, yes, at least in this world's standard)  
>  (一応 世の中的に **は** 俺は大人だろう **な** )
