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.

    5 ways to improve English test results

    By Charles Hamilton

    As with all tests, adequate preparation is crucial. For many aspiring migrants needing to take an English test, it may have been several years since they took an official exam. Knowing how to prepare effectively and what to expect on the day are key when it comes to securing a successful outcome. Use these five exam preparation tips below to improve your English test results.

    1. Familiarise yourself with the type of test questions you will be asked and know what to expect on the day

    The official guides published by the testing bodies are an excellent source of information to help you fast-track your learning. They offer materials that replicate the real test questions as well as guidance and strategies for dealing with every task set. Taking a practice test in exam-like conditions helps to improve time management skills and set realistic expectations on your potential performance.

    As with all high-stakes tests, security arrangements at the test center are strict. Test takers need to prove their identity via a passport or similarly approved document, so it’s a good idea toarrive at least 30 minutes beforethe test time and have your documents to hand.

    2. Give yourself enough time by setting clear, measurable and achievable goals. This will help keep your motivation up and your end goal in sight

    Start with a detailed understanding of your current English proficiency. That makes it easier to focus on any weaker areas ahead of taking the test and plan how long you’ll need to study for to bring your skills up to the required level.

    3. Seek English instruction that works for you and matches your specific needs and learning goals

    Coursebooks are a good option if you have a little more time to study in the run-up to the test. A rigorous preparation course structure will take you through a series of normally class-based lessons designed to prepare you for the test. Sometimes, however, the best way to prepare for a test is to join a class and receive tuition face-to-face. There is a multitude of courses and they offer class-based or individual tuition, from intensive week-long courses to six-month programs to help brush up on your English skills.

    4. Choose quality materials that are at the right level for you – they should stretch you a bit to help you progress so you stay motivated

    Digital learning can be very useful, providing opportunities to study at a time that suits and giving lots of feedback opportunities. Many test-takers take advantage of the large amount of free preparation material that includes everything from print and digital course guides to practice tests. A huge amount of information is also posted on YouTube, including tutorials and advice covering the range of different tests on offer.

    5. Be persistent – keep practicing at every opportunity

    Make the most of those spare minutes to practice your skills. Every workday includes a little downtime so try to incorporate a few short 5 or 10 minute practice activities each day to keep building your knowledge.

    IELTS has long been the standardized test approved by the Australian government and the test of choice for visa applicants both for work and study. Since November 2014, in an effort to make it more convenient for applicants, the DIBP has approved a number of additional tests that can be used as proof of English language skills, including TOEFL iBT, Cambridge English Advanced (CAE) and the  (PTE Academic).

    Bonus tip just for PTE Academic test takers

    PTE Academic offers a wide range of free and paid materials online that help test takers prepare for their migration visa English test. Of particular note is the which gives test takers an indicative score – so they know how close they are to their goal.
