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.

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.

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.

Hint: If you understand English articles ("a/an/the"), then think of "another" as "an + other." You can use "another" before a noun whenever you can use "a (n)" before a noun. The rules are the same. Another = an other! other + plural or uncountable nonspecific noun
