Is there a difference of meaning for following sentences? If so, why is the meaning different. Would examining parts of speech would show the reason of different meaning?
1) They support one another.
They = Pronoun. Support = verb. one = noun or pronoun? another = adj
2) They support another one.
They = pronoun. support = verb. another = adj. one = noun or pronoun?
In the sentence...

that's a correct sentence.
when a pronoun is used to denote the action done by the subject and on the subject it is called reciprocal pronoun.
