Forms of other are used as either adjectives or pronouns. These forms distinguish singular from plural, both as adjectives and pronouns.
The adjective another is used to modify singular nouns. Its plural counterpart, other, is used to modify plural nouns, noncount nouns, and collective nouns. Another means “one more of something” or “something different.” Other means “more things or persons” or “different things or persons.”
- I want another piece of cake, please. (one more)
- I don’t like this apple. I’d prefer another apple. (a different one)
- We met the other guests at the party. (more of them)
- They’re strange. I’d rather meet the other guests. (different ones)

- Some plants are wilted. Other plants seem to be thriving. (plural, others in general)
- These trees need to be sprayed. The other trees look healthy. (plural, specific others)
- This rose bush needs trimming. The other rose bush is perfect. (singular)
