Is なんだから is related to のだ?


I made sure to check if this had already been answered but I could not find
one. So my question is: is なんだから related to のだ? Looking at some example
sentences it seems to imply something like that but I'm not sure. I can't see
to find a definitive answer.




...なんだから is related to のだ through various processes at work here. There is a
simple contraction here, i.e. なんだから -> なのだから.

Let's split this phrase up into the individual bits: な+のだ+から.

The な is required before using のだ when the preceeding work is a noun or na-
adjective; in other words, in sentences that would end in です (だ). This is
similar to how sentences that end with ~と思う require the subphrase to be marked
with the copula (i.e. ~だと思います).

Hopefully this will help clear up some ambiguity.
