As a proofreader and editor, I'm often asked to explain the rules of grammar. I answered three of the most common questions in the first post of this series, and now it's time to look at another frequent query: how to use apostrophes.Where do they go? When are they needed? And when should they be left out entirely?

Apostrophes might be small but they can cause big confusion because they are used both to indicate posession and to contract words. But the good news is that there are clear, simple patterns to follow, which we'll explore, along with exceptions to watch out for.Whether you’re writing a report or just a text message, these tips will help you use apostrophes correctly and confidently.

Apostrophes with ease: posession

Apostrophes show possession: they tell us something belongs to someone or something.When we want to show possession for regular plurals (when a word needs an "s" to make it plural), the apostrophe goes at the end and no further "s" is added:

  • The teachers' association
  • The campaigners' letter
  • The dogs' dinner

Whereas, when we want to show posession for either a single noun or an irregular plural (for example, children, geese), we add an "apostrophe s":

  • Sarah's car
  • app's assessment tools
  • The children's presents
  • The geese's pond

Single names that end in an “s” get an “apostrophe s” but plural names get only an apostrophe:

  • Mrs Jones’s car
  • James's cat
  • Whole Foods’ offices
  • Starbucks' nearest store

There's one exception that's important to note: "its" and "it's". The posessive form "its" does not have an apostrophe: "it's" always means "it is".

  • The cat ate its food

Apostrophes with ease: contractions

Contracted words are the combined and shortened forms of two words, which are commonly used in everyday writing and speech to sound more natural and conversational. They're made by omitting certain letters and replacing them with an apostrophe: for example, in "don't", it replaces the missing “o” from not.

When you miss one or more letters, use an apostrophe:

  • "would not" becomes "wouldn’t"
  • "cannot" becomes "can’t"
  • "we are" becomes "we're"
  • and, as before, "it is" becomes "it's"

When not to use apostrophes

A common mistake is using apostrophes when making words plural or when refering to decades and numbers. For example:

  • The 1980s had the best music (not "The 1980's")
  • Many people retire from working in their 70s (not "their 70's")
  • I bought some apples at the store (not "apple's")

Test your knowledge

Now you know the basic rules of apostrophes, it's time to check your knowledge.

Which sentence is correct?:

  1. The childrens break time has finished
  2. The childrens' break time has finished
  3. The children's break time has finished

It's sentence 3. We want to show posession – break time belongs to the children – and "children" is plural so it gets an "apostrophe s".
Now try these sentences and see if you can figure out which one is right:

  1. When you're walking my dog, its important to remember it's collar.
  2. When you're walking my dog, it's important to remember its collar.
  3. When youre walking my dog, it's important to remember it's collar.

The correct answer is 2. "You're" is a contraction of "you are", "it is important" so we use "it's" and we show that the collar belongs to the dog by using "its". Finally:

  1. Luis' daughter won't go to sleep.
  2. Luis's daughter wont go to sleep.
  3. Luis's daughter won't go to sleep.

Here, the right answer is 3. "Luis" is a single name, so gets an "apostrophe s", and "will not" is shortened to "won't".

Hopefully you now feel more confident in using apostrophes in your writing. Look out for the next post in this series, where we’ll explore more common grammar mistakes and how to avoid them.

    Grammar: how to tame the unruly beast

    By Simon Buckland

    “Grammar, which knows how to control even kings”- ѴDZè

    When you think of grammar, “rule” is probably the first word that pops into your mind. Certainly the traditional view of grammar is that it’s about the “rules of language”. Indeed, not so long ago, teaching a language meant just teaching grammatical rules, plus perhaps a few vocabulary lists. However, I’m going to suggest that there’s actually no such thing as a grammatical rule.

    To show you what I mean, let’s take the comparative of adjectives: “bigger”, “smaller”, “more useful”, “more interesting”, etc. We might start with a simple rule: for adjectives with one syllable, add -er, and for adjectives with two or more syllables, use more + adjective.

    But this doesn’t quite work: yes, we say “more useful”, but we also say “cleverer”, and “prettier”. OK then, suppose we modify the rule. Let’s also say that for two-syllable adjectives ending in -y or -er you add -er.

    Unfortunately, this doesn’t quite work either: we do say “cleverer”, but we also say “more sober” and “more proper”. And there are problems with some of the one-syllable adjectives too: we say “more real” and “more whole” rather than “realer” or “wholer”. If we modify the rule to fit these exceptions, it will be half a page long, and anyway, if we keep looking we’ll find yet more exceptions. This happens repeatedly in English grammar. Very often, rules seem so full of exceptions that they’re just not all that helpful.

    And there’s another big problem with the “rule approach”: it doesn’t tell you what the structure is actually used for, even with something as obvious as the comparative of adjectives. You might assume that it’s used for comparing things: “My house is smaller than Mary’s”; “John is more attractive than Stephen”. But look at this: “The harder you work, the more money you make.” Or this: “London is getting more and more crowded.” Both sentences use comparative adjectives, but they’re not directly comparing two things.

    What we’re actually looking at here is not a rule but several overlapping patterns, or paradigms to use the correct technical term:

    1. adjective + -er + than
    2. more + adjective + than
    3. parallel comparative adjectives: the + comparative adjective 1 … the + comparative adjective 2
    4. repeated comparative adjective: adjective + -er + and + adjective + -er/more and more + adjective

    This picture is more accurate, but it looks abstract and technical. It’s a long way from what we actually teach these days and the way we teach it, which tends to be organized around learning objectives and measurable outcomes, such as: “By the end of this lesson (or module) my students should be able to compare their own possessions with someone else’s possessions”. So we’re not teaching our students to memorize a rule or even to manipulate a pattern; we’re teaching them to actually do something in the real world. And, of course, we’re teaching it at a level appropriate for the student’s level.

    So, to come back to grammar, once we’ve established our overall lesson or module objective, here are some of the things we’re going to need to know.

    • What grammatical forms (patterns) can be used to express this objective?
    • Which ones are appropriate for the level of my students? Are there some that they should already know, or should I teach them in this lesson?
    • What do the forms look like in practice? What would be some good examples?

    Existing grammar textbooks generally don’t provide all this information; in particular, they’re very vague about level. Often they don’t even put grammar structures into specific CEFR levels but into a range, e.g. A1/A2 or A2/B1, and none fully integrates grammar with overall learning objectives.

    At app, we’ve set ourselves the goal of addressing these issues by developing a new type of grammar resource for English teachers and learners that:

    • Is based on the Global Scale of English with its precise gradation of developing learner proficiency
    • Is built on the Council of Europe language syllabuses, linking grammar to CEFR level and to language functions
    • Uses international teams of language experts to review the structures and assess their levels

    We include grammar in the GSE Teacher Toolkit, and you can use it to:

    • Search for grammar structures either by GSE or CEFR level
    • Search for grammar structures by keyword or grammatical category/part of speech
    • Find out at which level a given grammar structure should be taught
    • Find out which grammar structures support a given learning objective
    • Find out which learning objectives are related to a given grammar structure
    • Get examples for any given grammar structure
    • Get free teaching materials for many of the grammar structures

    Think of it as an open-access resource for anyone teaching English and designing a curriculum.
