can we say " Don't mess with dirt over there. You have already taken the bath. Do you want to get dirty again? " ?
I think we can use "You have already taken a bath" although the "you just took a bath" sounds more natural.
Can we remove "a" before "bath" ?
Thank you very much !
No, you can't remove the "a".
For info: "take a bath" - AmE; "have a bath" - BrE
Is there any expression like "take two/three/four baths" ?
If it isn't, how can we express that meaning ?
Let me try first, "take three times of bath", is it correct ?
About your sentences?
Thank you very much !
Is the use of "bath" similar to the use of "milk", "coffee" as a countable noun?
E.g: "take a milk", "take a coffee"
Milk and coffee aren't countable nouns, are they ? So why can we use them as countable nouns in some contexts ? Is these the short ways of speaking (I mean "a milk" = "a cup of milk") or idioms ?
Is there any principle to do the same with other uncountable nouns ?
Thank you very much !
"To have/take a bath" is simply another way of saying "to bathe". It just makes it clearer that you're talking about doing so in a bathtub, as opposed to bathing in the sea.
"To have a coffee" is indeed just a short way of saying "To have a cup of coffee".
It doesn't work with all uncountable nouns though. "Bread", for instance, is uncountable but we wouldn't say "I'll have a bread" instead of "I'll have a slice of bread".
So "bath" here is a real countable noun. (and also an uncountable noun as I know) ?
Does "two milks" mean "two cups of milk" ?
Did you mean we don't have any principle to know what uncountable nouns can be used as countable nouns like "milk", "coffee" ?
We must remember all these to use in right contexts, mustn't we?
If so, can I get all list of these nouns to learn ?
Thank you very much !
I guess "two milks" would mean "two cups/glasses of milk" if you were ordering them in a café or something. I don't think I've ever heard it but that doesn't mean it's wrong. I just don't drink plain milk and nor do any of my friends!!!
I don't think there's a rule you can learn for nouns that can be countable and uncountable. However, I found this website which might help:
