Other, Another, Others: The Three-Way Split Explained

1Another is two words pushed together

This whole topic becomes much easier once you notice something about the spelling that nobody points out.

Because another contains an, it can never go with a plural. "Another books" is exactly as wrong as "an books", and for the same reason. It also cannot go with an uncountable noun, because "an water" is wrong too. Once you see the hidden an, you stop needing a rule.

• another book — correct, singular countable
• another books — wrong, an cannot take a plural
• another water — wrong, an cannot take an uncountable
• other books — correct, no article involved
• other water — correct

So the first decision is mechanical rather than semantic: is the noun singular countable? If yes, another is available. If it is plural or uncountable, you need other.

Tip: Whenever you are about to write another, silently say "an other" instead. If that sounds wrong, another is wrong too.

2Another: one more, singular only

Another has two closely related meanings, and both are restricted to singular countable nouns.

• Another cup of tea, please. — one more
• Let's meet another time. — a different time
• That's another problem entirely. — a different one
• I'll need another five minutes. — a special case, see section eight

Another also works as a pronoun with no noun after it: "I've finished this one, can I have another?" This is common and completely natural.

Tip: Another one is a very common phrase and worth having ready: "Can I have another one?" works when you cannot remember the noun or do not want to repeat it.

3Other: with plurals and uncountables

Other is the form you need whenever another is blocked, which is whenever the noun is plural or uncountable.

• other books, other people, other options — plural
• other water, other information, other advice — uncountable
• Do you have other colours? — plural
• Other students complained. — plural
• I have other work to do. — uncountable

This is the single most useful distinction in the whole topic. Other before a noun: no -s. Others with no noun after it: -s. Two rules, and between them they cover the majority of what learners get wrong.

Some other and any other are common combinations: "some other time", "any other questions?" Both follow the same rule — no -s, because a noun follows.

Tip: Test yourself: is there a noun immediately after? If yes, other. If no, others. That is the whole -s question.

4The other: the specific remaining one

Adding the changes the meaning from "an additional one" to "the specific one that is left", and it is the article doing all the work.

"I have two brothers. One is a doctor and the other is a teacher." There were exactly two, one has been mentioned, so the other is fully identified. Compare "another brother", which would mean a third one you had not mentioned.

• One shoe is here; where is the other? — of a known pair
• The other side of the street — there are only two sides
• I'll take this one and you take the other. — two items
• The other day — an idiom, see section ten

The other is singular when the remaining item is one thing, and it can also take a plural noun: "the other students" means all the remaining students in a known group.

The contrast with another is the point. Another book = one more, from an open set. The other book = the specific second one, from a set of exactly two. If you can count the set and there is only one left, use the other.

Tip: If you find yourself gesturing at something specific while speaking, you almost certainly want the other rather than another.

5Others: the pronoun with the -s

This is where the -s finally appears, and the rule for it is simple and absolute.

• Some people agreed; others disagreed. — no noun after others
• Some students passed; others failed. — correct
• I have some ideas, do you have others? — correct
• Others books are cheaper. — wrong; use Other books
• Others say it's too expensive. — correct, others as subject

Others always means "other people" or "other things" without naming them. "Others disagreed" is short for "other people disagreed". Once you see it as a replacement rather than a describer, the -s stops feeling arbitrary.

The pairing some… others… is extremely common in writing, especially when describing a divided group: "Some found it easy; others struggled." It is a useful structure for exam essays because it presents two views cleanly.

Tip: The pattern some… others… is worth practising as a unit. It appears constantly in opinion writing and it demonstrates range in a way examiners notice.

6The others: all the rest of a known group

Adding the to others narrows it from "some unspecified people" to "all the remaining members of a group we both know about".

"Three of us stayed; the others went home." There was a defined group, three stayed, and the others is everyone left in it. Compare "others went home", which would mean some unspecified other people did — not necessarily from your group.

• Two students passed; the others failed. — the rest of that class
• I'll wait here; the others can go ahead. — a known group
• Where are the others? — the rest of our party
• Some agreed, others didn't. — unspecified people, no defined group

The difference between others and the others is the same difference as between some people and the rest of them. Without the, the group is open. With the, it is closed and complete.

The rest is an everyday alternative to the others and works with both countable and uncountable nouns: "the rest of the students", "the rest of the water". In conversation it is more common than the others.

Tip: Where are the others? is a genuinely useful phrase when travelling in a group, and it is one of the clearest illustrations of what the adds.

7The complete decision table

The whole topic reduces to two questions: is there a noun after the word, and is that noun singular?

• one more, singular countable → another → another coffee
• different ones, plural → other → other books
• different, uncountable → other → other information
• the specific remaining one, singular → the other → the other shoe
• the specific remaining ones, plural → the other → the other students
• some unspecified ones, no noun → others → others disagreed
• all the rest of a known group, no noun → the others → the others left

Notice that the table has no row for "another" with a plural or an uncountable noun. That combination simply does not exist, because of the hidden an.

Tip: If you can remember only one thing: the -s goes on when the noun goes away.

8Another with numbers and time

There is one apparent exception to the singular rule, and it is common enough to be worth understanding rather than memorising.

"I'll need another five minutes" looks like another with a plural, which section one said was impossible. But five minutes here is being treated as one block of time, not as five separate minutes. English is counting the block, and the block is singular.

• another three days — one period of three days
• another twenty pounds — one amount of money
• another two hundred kilometres — one distance
• another few minutes — a common, slightly informal version
• another books — still wrong, books is not a measured quantity

The test is whether the plural functions as a single unit of measurement. Minutes, dollars, kilometres and weeks pass it; books, people and questions do not.

A further and an additional work similarly and are more formal: "a further two weeks", "an additional five hundred dollars". These are common in business and academic writing.

Tip: Another ten minutes is one of the most useful phrases in everyday English — for delays, for waiting, for asking someone to hang on. Learn it as a chunk.

9Each other and one another

Two reciprocal pronouns built from other, used constantly and slightly mishandled by most learners.

Each other and one another mean the same thing: A does something to B and B does the same to A. "They looked at each other." "We help one another." There is a traditional rule that each other is for two people and one another for three or more, but almost nobody observes it and neither is wrong in modern English.

• We see each other every week. — correct
• We see us every week. — wrong, needs each other
• They helped one another. — correct
• They helped themselves. — different meaning entirely
• each other's names — the possessive

The important contrast is with reflexive pronouns. "They looked at themselves" means each person looked in a mirror. "They looked at each other" means they looked at the other person. Many languages use one form for both, which is why this error is widespread and why it produces genuinely odd sentences.

The possessive is each other's, with the apostrophe before the s: "We know each other's families." Not "each others' families" — the other is singular here.

Tip: If your language uses a reflexive form for reciprocal meaning, drill "we see each other" against "we see ourselves" out loud. The difference is large and the error is very visible.

10Other than, otherwise and the other day

Three fixed expressions built on other that behave nothing like the grammar above.

• in other words — rephrasing
• on the other hand — presenting a contrast
• every other day — alternate days, not every single day
• the other way round — reversed
• none other than — emphatic introduction

Tip: On the other hand and in other words are two of the most useful discourse markers in English writing. Both appear in strong exam answers and neither is difficult to place.

11Thirty sentences, corrected

Cover the right-hand side and fix each one before you look. These are the errors that appear most often in real learner English.

• I need another books → I need other books
• Others people disagreed → Other people disagreed
• Do you have an other one? → Do you have another one?
• Some agreed and other disagreed → Some agreed and others disagreed
• I have two sisters; one is a nurse and another is a teacher → …and the other is a teacher
• Where are others? (of our group) → Where are the others?
• Can I have another water? → Can I have some more water?
• I'll need other five minutes → I'll need another five minutes
• We see us every weekend → We see each other every weekend
• They looked at themselves and smiled (at one another) → They looked at each other and smiled
• We know each others' families → We know each other's families
• I go to the gym every other days → I go to the gym every other day
• Other than of the price, it was good → Other than the price, it was good
• In others words, it failed → In other words, it failed
• On other hand, it's cheaper → On the other hand, it's cheaper
• I saw him other day → I saw him the other day
• I have seen him the other day → I saw him the other day
• Some students passed, the other failed → Some students passed, the others failed
• Do you have any others questions? → Do you have any other questions?
• This shirt is too small, show me other → …show me another one
• The others side of the road → The other side of the road
• I have another work to do → I have other work to do
• Let's meet other time → Let's meet another time
• Hurry up, other we'll be late → Hurry up, otherwise we'll be late
• There were three of us; two left and other stayed → …and the other stayed
• Some people like it, others don't → correct as written
• I'll take this one, you take the other → correct as written
• We helped one another during the move → correct as written
• Another two weeks and we're done → correct as written
• Other information is available online → correct as written

Tip: Five of these are already correct. The last one is worth a second look — other with an uncountable noun and no article is perfectly normal.

12Noticing the -s in real speech

The whole distinction rests on a single unstressed consonant at the end of a word, which makes this a listening problem as much as a grammar one.

In connected speech, others often runs straight into the next word and the -s becomes almost inaudible, particularly before a consonant. "Others said" and "other said" sound nearly identical at speed. If you have only met these forms in writing, you will not hear the difference — and worse, you will assume native speakers are dropping it, which they are not.

The upside is that the grammar gives you a free check. Because others can never be followed by a noun, if you hear a noun immediately after, it was other regardless of what your ears reported. The rule repairs the listening gap.

• Listen for some… others… in interviews and opinion pieces — it is everywhere
• When you hear other, check whether a noun followed; that tells you which form it was
• Collect each other and one another as whole chunks, never as separate words
• Save the full phrase, since the noun after it is what determines the form
• Describe a divided group out loud: some… others… — say it three times

Saving the phrase matters more here than usual, because other on its own carries none of the information you need. Other students, the other one and others entirely teach three different rules, and only the surrounding words distinguish them.

Tip: FlexiLingo puts interactive subtitles on YouTube and podcasts, so you can click any word to see its meaning and CEFR level and save it with the full sentence — which is what makes the -s visible even when it is not audible.
