What is the difference between "nötig" and "notwendig"? When would one be preferred over the other, or are they always interchangeable?

Is the meaning different?Looking at the etymology of both adjectives sheds some light on the subtle differences in the meaning of "nötig" *vs. "notwenig":
Are "nötig" or "notwenig" interchangeable?In most cases "notwenig" can be replaced by "nötig" in contemporary German but "nötig" can not always be replaced by "notwendig". This is mostly the case in colloquial usage, when an an idiomatic expression is involved, as has already been said in conjunction with "haben", or in a more figurative meaning.

Some examples: «Notwendig»
