In the BBC website Learning English a person gives some examples of the phrase "clean up one's act" and one example is:
I used to drink a lot of alcohol but when I got ill, I decided to clean up my act and now I only drink cola!
My question is: is it correct to use only before the verb it modifies?
Generally we should place “only" next to the noun, subject, verb, or phrase we're trying to modify.
So, I think it should be like I drink only cola. Am I right?
And is the sentence I drink cola only right grammatically?
I saw in many shopping malls the price was written as 1000₹ only etc. Is it right to say like this? Please explain to me the grammar relative to this.
