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.

Other, the other and another can be pronouns. They have the same meanings as before: 'alternative' or 'additional'. In addition, when other is a pronoun it can be made plural: others.

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!

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)
