I am wondering what the difference is between "ones", "the ones", "one", the one", "those", and "that"?
Take a noun for example. Some people say a dog=one, dogs=ones, the dog=the one=that, and the dogs=the ones=those. It's a rule of thumb, but what I found was that this is not always correct. There are exceptions.
For example, in the case of "A chair made of wood is as good as one made of leather", this sentence is equal to "A chair made of wood is as good as a chair made of leather". The two sentences are different from "A chair made of wood is as good as that made of leather." or "A chair made of wood is as good as the one made of leather.", because they are not talking about specific ones, the determiner "the" and the pronouns that represent "specific ones", such as "that", are not needed here.
However, when it comes to plural nouns, there are exceptions.
Chairs made of wood are as good as ones made of leather=Chairs made of wood are as good as those made of leather.
Some people may argue that "those" refer to "specific ones", but in this case, it somehow refers to all of the chairs made of leather in general.
However, if we change it to
Chairs made of wood are as good as the ones made of leather.
Chairs made of wood are as good as the chairs made of leather
The meanings are different. It seems that "those" is sometimes equal to "ones", especially when we compare things, while "one" is never equal to "that"
What do you think about it?
All opinions and advice are welcome.
Thanks in advance!
