other(s) and another
other and others
When other is used with a noun it has no plural form.
- Where are the other photos? (not
… the others photos?)
But used alone, without a noun, it can have a plural form.
- I’ve got one lot of photos. Where are the others?
- These are too small. Have you got any others?
Normally, other(s) is only used alone if it refers to a noun that has been mentioned before. An exception is the common plural use of (the) others to mean (the) other people.
- He never thinks of others.
- Jake’s arrived – I must tell the others.
- but not
On the phone, one cannot see the otherorHe never listens to another
Not used like an adjective
Other is a determiner or pronoun; it is not used exactly like an adjective. So it cannot normally have an adverb before it, or be used after a linking verb.
- I’d prefer a completely different colour. (not
… a completely other colour.) - You look different with a beard. (not
You look other …)
For one another, (see here).
‘additional, extra’
Another (spelt as one word) can mean ‘an additional, extra’. It is used with singular countable nouns.
- Could I have another piece of bread? (not
… an other piece of bread.)
Another can be used without a noun, or with one, if the meaning is clear from what has come before.
- Those cakes are wonderful. Could I have another (one)?
With uncountable and plural nouns, we normally use more, not other, with this meaning.
- Would you like some more meat? (not
… other meat?) - Would you like some more peas? (not
… other peas?)
However, we can use another before a plural noun in expressions with few or a number.
- I’m staying for another few weeks.
- We need another three chairs.
For other cases where a(n) is followed by a plural, (see here).
‘alternative’
(An)other can also mean ‘(an) alternative’, ‘besides / instead of this/these’.
- I think we should paint it another colour.
- Have you got any other cakes, or are these the only ones?
Other people often means ‘people besides oneself’.
- Why don’t you think more about other people?
