Hey
gmdsatHappy to add clarity to the uses of 'as'.
"As" as Conjunction:'As' can be used as a connector to join a dependent clause of time, manner, reason, comparison, concession/contrast, and even additional information. For example:
a. As he grew older, he grew naughtier. (Time)
b. Do as I do. (Manner)
c. I borrowed money as I was completely broke. (Reason)
d. Improbable as it seems, it is true. (Concession/Contrast = though)
e. Her hair is as soft as silk (is). (
Comparison)
f. As you may have heard, Rishi Sunak has been elected the PM of the United Kingdom. (Additional Information)
'As' as a preposition:As can be used to introduce specific examples or roles. For example:
a. Various trees, as oak or pine, are used to make furniture. (Specific examples; similar to 'such as')
b. I speak to you as a friend and not as a teacher. (Role/Capacity)
So, yes, "as" can certainly be followed by nouns. What matters is the meaning associated with each application. Adopting a meaning based approach to learning these roles will be far more fruitful than focusing narrowly on grammatical jargon.
I hope this improves your understanding.
Happy Learning!
Abhishek
