Thank you very much for your explanation. Could you please kindly explain what meaning "take as" has?
Looking forward to hearing from you.
Thank you in advance.
"Alright, I'll take that as a request for more information." (regard as)
The meaning here is straightforward. It's not an idiom. It has a range of meanings depending on the context and the meaning of "take."
"Will you take this as full payment?" (accept as)
"Don't try to change me! Take me as I am." (accept as)
All these sentences could use "for".
"Will you take this for full payment"
"Take me for what I am"
But it's best to use "as".
