ANOTHER vs OTHER vs OTHERS vs THE OTHER
Examples:
One girl was wearing a white dress. The other girl was wearing a red one.
(‘Other’ is describing or qualifying the noun ‘girl.’ So, it’s an adjective.)
(‘Another’ is qualifying ‘girl’ so it’s an adjective; only used with singular nouns because it means ‘one other.’]
[‘Other’ is still an adjective. Adjectives are invariable, so they never change for singular or plural. In this case, ‘girls’ is plural, but ‘other’ doesn’t change because it’s an adjective.]
Other, the other, another are adjectives when they are describing a noun.
In the following sentences we don’t want to repeat the word ‘girl’ so we use a pronoun. If we
refer to one girl we use ‘other’, and if there are more girls we use the plural ‘others.’ ‘Another’
means one more, so it’s only used to replace a singular noun.
(‘The others’ is replacing ‘the other girls,’ so it’s a pronoun. Pronouns change for singular or plural.)
Other, the other, another are pronouns when they are replacing a noun. They can be singular or plural.
Both are pronouns, that is, they stand for a noun. ‘Others’ is more vague, we are not determining how many others, or which other ones. ‘The others’ is more specific; it stands for all the rest.
