Quite clear to me is the use of very before an adjective. It emphasizes. But then, when very is used before a noun, it confuses me.
Furthermore, if it's before the noun which is not definable in degrees or intensities, is using 'very' okay? In other words, is it okay to use very before a noun that you simply cannot emphasize?

If it applies to 'undegreeable' nouns, this sentence should be 'okay', shouldn't it? -- The very death of the father shook the entire family.
Also, in such usage, very looks both to me -an adverb and an adjective.
