You need to stop considering "another" as one word. It's not. It's really two words which are one in writing only. "An other" is written as "another" for some reason. You just need to know when to use the indefinite article, and if it happens to be next to "other", remove the space. "Other" can be both a noun and an adjective. This rule applies to both forms.

I want another dog. (I have one, and I'd like to get an additional dog) I don't like that small dog, I'd prefer the other (I don't want the small one. I want something different) There is no need to put an article (a, an,the) before "another". This is incorrect: He didn't ask for the another position. This is correct: He didn't ask for another position. I hope this helps!

"Another" is used with singular nouns. "Other" with singular or plural. E.g Have another cup of tea. Let's meet another day. There are other jobs you could try. This book has other information.

Ex : I was going to another country can you see " to " ? if you see " a , e , i , u, o " in last word you must use " another "
