The primary difference between another and other is that both another and other are determiners, but another precedes singular countable nouns or pronouns. Conversely, other precedes a plural countable as well as uncountable nouns and pronouns.

The words another and other mean the same thing, except that another is used with a singular noun and other is used with uncountable and plural nouns: She’s going to the cinema with another friend. She’s going to the cinema with other friends.

When it comes to distinguishing between “other” and “another,” the main difference lies in their usage with countable and uncountable nouns. “Other” is typically used when referring to more than two things or people, while “another” is used when referring to one additional thing or person.

A simple rule to help you remember the difference between another and other is: Another means: Another is a determiner (and a qualifier) that goes before a singular countable noun or a pronoun. Another can be followed by a singular countable noun. He has bought another motorbike.
