Mohammed is correct that we use 'other' for plural words and 'another' for singular words, but it isn't quite so simple. This is the rule: We use 'another' only for: *singular, countable, indefinite nouns = another book We use 'other' for all other situations: *plurals = other books *singular definite nouns = that other book, the other book, your other book *uncountables = other information Bear in mind that 'another' is just a combination of the article 'a'/'an' and 'other'. An + other = Another 'Another' just means ONE OTHER. That's what you need to remember.

Both words are adjectives. "Another" is derived from "an other" and is ALWAYS singular. Give me another ONE. "Other" can be singular or plural. Is there any other type? Are there any other types?

Mohammed is right. I am replying to answer provide a few more examples: "How many other people are coming?" This question may be asked when going to a party. It is implied that there will be many people there so you would use "other" which would mean outside the people speaking, how many more people would be at the party. "Can I have another piece of bread?" This is singular and can be asked when you have some bread, but want one more piece. "What is the other meaning?" Here "other" is a singular. Since it is "the other" it implies there is some other meaning to the word or phrase being asked about. Before this question, a person could ask "Is there another meaning?", which would expect a yes/no answer. Once you know there is another meaning, you can ask "what is the other meaning?"

Thank you! :)

Hi, we use other for the plural noun "like: Other choices" But another is used for singular noun "like: Another choice"
