When buying something, what it more suitable to ask the seller?
How much does it cost?
How much is its cost?
I know that the word "cost" is a verb and noun as well, but my question is what is the acceptable way - if there is.
Both sentences are grammatically correct. I would have to say that both are acceptable.
However, the questions "How much does it cost?" and "What does it cost?" are very common in my dialect. The question "How much is its cost?" sounds formal, foreign, or oddly emphatic.
My dialect is American, so feel free to ignore me if you prefer to emulate some other dialect.
Thank you for your interest in this question.
