The biggest difference between these two words is that “another” is always singular and does not describe anything specific. “Other” is used for plural and noncount nouns that are general. We only use “the other” to refer to specific nouns.

Unlike another, which is used as a determiner before singular count nouns, the word other is used as a determiner before plural or uncountable nouns. For instance: other cities, other people, other places, other information, other music, etc. Other means additional or extra, alternative, or different types of things or people.

A simple rule to help you remember the difference between another and other is: another + singular noun other + plural noun others (a pronoun to replace other + plural noun) I need another cup. (cup is singular so we use another) I need other cups. (cups is plural so we use other) I need others. (refers to other cups)

“Other” acts as an adjective or a determiner for plural and noncount nouns, representing general, additional, or distinct items. Conversely, “another” works exclusively with singular nouns. Unlike “other,” “another” does not refer to anything specific and implies one more item or an alternative of the same kind.

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.
