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.

    Reaching exam success with happiness and wellbeing in mind

    By Sophia Fergus

    Are you or your students preparing for an exam like ? If so, you might find that things are more stressful than usual or that motivation is starting to lack. When preparing to take an exam, it’s easy to overlook the fact that people also need to destress and relax a little.

    Exam preparation is an important period. That’s why we’ve come up with some tips and advice that will help increase happiness and well-being. It will also help develop good study habits and ensure you or your students remain happy right up to their exams and beyond.

    1. Create a study plan

    A clear plan can help you get off to a positive start. At the same time, it will inevitably lead to more confidence and better results on the big day. Make sure to gather all the materials and equipment you will need (or provide your students with a list of what they need to gather). Once prepared, set up a comfortable workspace where you will feel happy to spend time. If you’re a teacher, you can ask your students to describe their ideal study spaces in class – this will help them visualize what they need to do at home!

    It's also helpful to create a schedule where you write down what you need to work on and when. Try to include all areas of the exam but prioritize those areas that may need more work and improvement.

    2. Take time out

    If you're starting to feel anxious or stressed as the exam day comes nearer, here are some ideas to help manage:

    Take a break

    It’s better to study for short periods rather than spending hours on end at their desk. It’s a good idea to break up study periods and take a short break at regular intervals. If possible, also go outside and get some fresh air at least once a day.

    Try mindfulness techniques

    Guided meditation apps such as or can help reduce stress and prepare learners to focus better on their studies. You can also find guided meditation videos and audio tracks on Youtube or Spotify.

    Be positive

    Remember how far you’ve progressed and celebrate what you can do, and if you’re an educator encourage them to visualize themselves confidently completing the exam.

    3. Have fun!

    Although exam practice and reviewing are important parts of preparing for an exam, you can also have some fun. Play games and base activities around a variety of different media, including short videos and podcasts and other forms of entertainment.

    Make English a part of your leisure time. Watch series or films in English, listen to music or choose podcasts related to your interests. A good tip is to look for English-language alternatives to any materials or media usually consumed.

    4. Stay healthy

    The stress caused by exams can result in bad habits, and eating unhealthily – fast food, snacks and caffeine can provide a false sense of energy. However, the food we eat and drink can greatly affect our body and mind. A healthy diet can improve our mood, our memory and our levels of concentration:

    • Healthy carbs such as brown rice, pasta, whole grain bread and cereals will provide the necessary energy to allow students to keep working through the day.
    • Oily fish like salmon and sardines are great for the brain, heart and joints, as well as increasing serotonin which makes us feel good!
    • Other sources of Omega 3 such as nuts and seeds are a great substitute for vegans.
    • A variety of fruits and vegetables will ensure that students have a balanced diet that will improve memory, brainpower and mental agility.

    5. Get a good night’s sleep

    Sleep is essential for learning to take place. The time you spend asleep is just as important as the time you spend awake. You should aim to sleep for 8 hours a night. This will help your brain to recharge, allowing you to start the day with energy and focus.

    It’s especially important that you sleep well the day before the exam. This will help you relax and ensure that you are alert and ready to give your best performance.

    6. Offer incentives

    If you are studying intensively or for a long time, motivation levels may start to drop. If you’re a teacher and you see this is the case, your class will need some additional support and encouragement to help them keep going. Small rewards can help with this.

    Teacher: You can offer rewards in class by allowing students to choose an activity they enjoy, but it’s also useful for students to give themselves rewards for any goals they set and accomplish. This personalization will make the reward even more satisfying.

    Self-learner: When you get to certain checkpoints of your study make sure to reward yourself with something small that you enjoy. Small rewards include things like listening to your favorite song, eating a sweet treat or watching a funny video.

    7. Reduce the workload

    As the exam approaches, make sure to gradually slow down. Rather than trying to learn something new, spend the last few days reviewing what you’ve studied and practice English as much as you can. On the day before the exam, do something completely different, like go for a long walk or watch a good film. Just to get your mind to wind down and relax before your exam, which will likely be quite demanding on the brain.
