Sorry, I don't get what you exactly mean.He says this:
By bringing together this enormous group of pinheads, uh, I am, you know, in in many respects finding an engine of the economy that has been absolutely untapped—a vein of of energy.
Notice my use of a dash, which I believe should answer your question.
No, you can't use an adjective before a determiner: "Absolutely untapped a vein of energy." - wrong. "An absolutely untapped vein of energy." - correct.Ok, I get it. Thanks. Now, still, I want to know whether the phrase "absolutely untapped a vein of energy" is grammatically valid in some case? Thanks for the help.
Ok, I get it. Language is interesting. A lot of nuance and subtlety.The grammar seems to be fine. What that means is another story.
The reason I raise this question is that, to my English knowledge, we usually put the adjective after the article "a/an" and before the noun, such as, "an untapped market", not "untapped a market"
I knew the original sentence. Thank you for your explanation. I just intended to discuss some grammar regarding the order of adjectives and articles in front of a noun, which in itself had nothing to do with the original sentence.Your question shows you still haven't understood the original sentence. There is no adjective before the article. Let me try to show you once more:
... absolutely untapped—a vein of energy ...
The adjective untapped and the article a are not grammatically connected. You cannot consider the adjective to be appearing before the article. The red and blue parts are not connected.
