What is Each Other?
Each Other is considered a formal phrase. Conventionally, it is used during an informal conversation.
When we write something unofficial or informal, we do use the term Each Other. It is used to refer to two things or people only.
When referring to more than two things, Each Other is Grammatically a wrong usage of words. It might not look absurd with the sentence, and new learners or beginners might find it really confusing.
This is why their application in sentences is really essential
People who mainly practice spoken English get confused with this particular usage. They tend to mistake it as a single word. When we spell it out, it sounds co-dependent.
However, they are two separate words. Both Each and Other have their own separate meanings.
However, when we add these two in a sentence, it gives a completely new meaning.
Let us take an example: She and her best friend surprised each other. Here in this sentence, we can see that the number is restricted to two.
It means we can see only two individuals are involved. For such sentences, using Each Other is grammatically perfect and sound.

What is One Another?
One another is considered as a formal phrase. Conventionally, it is used during a formal conversation. When we write something official or formal, we use the term One Another.
It is used to refer to three things or more.
It is mainly used when we are referring to more than two things. There is no logical reasoning behind it, but it fits better when we use it in a sentence.
This is why it is really important to apply grammatical terms in sentences. A lot of times, this process is proven useful in avoiding mistakes.
People who are new to English Grammar can get even more confused. They tend to get confused between One Another and Another One.
These two are not only different phrases but have completely different meanings.
Another one means to ask for a different one. Also, it depends on the sentence we are using it in. The meaning varies accordingly.
It might also mean exchanging a particular thing with the same type. Also, it can mean adding another thing of the same type.
This is the reason it is important always to consider the sentences.
Let us take an example: The group of friends hugged one another. Here we can spot more than two people are referred to.
In such a sentence, One Another is the right fit. In modern English, people do not seem to put much focus on syntax.
However, using other phrases as synonyms might not be grammatically sound.
