I just want you to know,
And i know not what the younger dreams,
Some vague utopia, utopia
The structure I know not what the... sounded a bit weird to me. After doing some research, the closest similar grammatically valid structures(from oxford) that I found are:
- Treating the symptoms and not the cause. (negative of the cause).
- How was it? Not so bad. (Not very close to the actual lyrics).
I also think the lyrics could be using archaic English, when I know not, I run not etc were permissible in English. Please explain if the lyrics is grammatically correct, and if yes, what rule is it using.
