Another is formed from a combination of the words "an" and "other", and has a meaning similar to "one other".
* When used as an adjective,
another can precede only a singular countable noun.
* When used as a pronoun,
another takes a singular verb.
e.g. Please bring me another knife.
Another of her uncles lives in Montreal.
In the first example, another modifies the singular noun knife.
In the second example, the pronoun another is the subject of the singular verb
* Another usually cannot be immediately preceded by a determiner.
- The another student is nine years old. (WRONG)
Other can be used with singular countable, plural countable or uncountable nouns.
e.g. The other door is open.
The other streets are paved.
Do you have any other luggage?
In these examples, other modifies the singular countable noun door, the plural
countable noun streets, and the uncountable noun luggage.
*When used before a singular countable noun, other usually must be preceded by
e.g. Please pass me the other cup.
I do not know any other way to
There must be some other explanation.
In these examples, other is used with the singular countable nouns cup, way and
explanation, and is preceded by the determiners the, any and some.
*When other modifies a singular countable noun, the noun is sometimes omitted,
particularly in the expression one ... the other.
e.g. I have two pens. One is green and the other is blue.
One of my parents is a teacher; the other is a doctor.
Others is a pronoun. Others can be used to take the place of the word other, followed by a plural countable noun.
e.g. Those trees are hemlocks; the others are pines.
Ten people belong to the group, and five others are planning to join.
In the first example, others takes the place of the words other trees. In the second example, others takes the place of the words other people.
*Others is often used in the expression some ... others.
e.g. Some books are easy to read, but others are quite difficult.
Some people like classical music, while others prefer jazz.
/ ONE ANOTHER
We use the reciprocal pronouns each other and one another when two or more people do the same thing. Traditionally, each other refers to two people and one another refers to more than two people, but this distinction is disappearing in modern English.
- Peter and Mary helped one another.
= Peter helped Mary and Mary helped Peter.
- We sent each other Christmas cards.
= We sent them a Christmas card and they sent us a Christmas card.
- They didn’t look at one another.
= He didn't look at her and she didn't look at him.
We also use the possessive forms each other’s and one another’s:
They helped to look after each other’s children.
We often stayed in one another’s houses.
NOTE: We do not use reciprocal pronouns as the subject of a clause.
- You should take these pills every other day.
(take it one day, do not take it the next day, take it again the following day)
- Write every other line when I dictate.
(skip one line every time)
