I've always been fascinated by language and writing: as a child, I wrote newsletters for my classmates and books about my imaginary friends' adventures. That love of words eventually led me into a career as a writer, editor and proofreader. Over my career, I've checked thousands of reports, articles and blogs – and I see the same grammatical mistakes time and time again.

In this blog series, I'll share my favourite tips and tricks to help you remember those tricky grammar rules; whether you're writing for work, to learn or just for fun, these posts will help you improve your English and write with more confidence. Here are the top three grammar rules that people ask me to explain:

1) "Which" or "that"?

2) "Less" or "fewer"?

3)"Me" or "I"?

"Which" or "that"?

We use "that" to introduce a phrase that is essential for fully understanding a sentence. For example, if a colleague asks you to "Join me in the meeting room that has a red door", then this tells us that there is more than one meeting room, but only one has a red door. Without this piece of information, you won't know where to meet your colleague. Phrases like this that hold essential information are called "restrictive clauses".

In comparison, “which” introduces additional information that isn’t essential for understanding the sentence’s meaning. At a different office, if your colleague asks you to "Join me in the meeting room, which has a red door", then this tells us that there is only one meeting room and it happens to have a red door. You don't need to know the colour of the door to understand where to meet. These are called "non-restrictive clauses" and are separated with commas, unlike restrictive clauses.

Also compare:
"Simon brought his dog that has three legs." (This tells us that Simon has more than one dog and only one of those dogs has three legs.)

"Jada brought her dog, which has three legs." (This tells us that Jada only has one dog. The dog also happens to have three legs.)

"Less" or "fewer"?

"Fewer" is for items that you can count: it means "not as many".

"Less" is for mass concepts: it means "not as much".

For example: "I'm trying to have less sugar in my diet. As part of this, I'm going to have fewer spoons of sugar in my coffee."

Another example: "I had less time to work this week, so I did fewer hours on the assignment."

"Time" is uncountable but "hours" are countable.

"Me" or "I"?

Should you say “Jane, Carlos and I went to the movies?” or “Jane, Carlos and me went to the movies?”

Use "I" when you're doing something – when you are the "subject" of the sentence.

Use "me" when something is being done to you – when you are the "object" of the sentence.

So, "I" is correct here. Here's the easiest way to know which one to use: remove the other people from the sentence and see if it still makes sense.

Incorrect: “Me went to the movies.”

Correct: “I went to the movies.”

Therefore, it's correct to say: “Jane, Carlos and I went to the movies.”

That's when you're the subject of the sentence, now compare it to a case when you're the object.

Incorrect: "Jane invited I to the movies."

Correct: "Jane invited me to the movies."

Bonus tip: remember to always put other people first. So, in our first example, it is always "Jane, Carlos and I", rather than "I, Jane and Carlos".

Grammar can be tricky, but it gets easier with practice – and a few insider secrets. Look out for the next post in this series, where we’ll explore more common grammar mistakes and how to avoid them.

    Understanding resolutions: Setting your language goals for success

    By Charlotte Guest
    Reading time: 3 minutes

    Millions of people make resolutions every New Year (or any significant milestone). Many learners set inspiring goals to acquire new skills, explore new academic fields, or develop better study habits. But how often do these resolutions stick? And how can you turn your learning-related goals into lasting habits? This post dives into the science of resolutions and practical strategies to make your learning commitments stick.

    Why do learning resolutions fail?

    that the majority of New Year’s resolutions fail by February. When it comes to learning, the reasons often include overly ambitious goals, lack of clear plans and failure to sustain motivation over time.

    One main reason resolutions fail is that they are not specific enough. Goals like "get fit" or "learn a language" are too vague and don’t include steps to take. Without a clear plan, it’s easy to feel lost and lose motivation.

    For example, it’s one thing to decide, “I’m going to learn French this year,” but without a structured plan, consistent practice and measurable benchmarks, the resolve often fizzles out.

    Another factor is having unrealistic expectations. While it's good to be ambitious, setting too high goals can cause frustration and burnout. For example, trying to master a skill in just a few weeks ignores the time and effort needed to improve.

    Distractions and other priorities can slow down progress. Life demands, like work or family, can easily push resolutions aside if they aren't included in everyday routines.

    How long does it take to form a habit?

    One key to sticking to a learning resolution is habit formation. Popular belief often quotes the “21-day rule,” but research says differently. A 2009 study published in the found that it takes an average of 66 days to form a new habit.

    However, this number varies based on personal factors, the difficulty of the habit and the surroundings. For instance, if your goal is to study for 20 minutes each day, it may feel more comfortable after a few weeks of practice. In contrast, picking up a harder learning habit, like spending two hours a day studying Mandarin grammar, could take much longer to become a regular part of your routine.

    Strategies for making resolutions stick

    1. Start small and specific

    Instead of setting a big goal like “become fluent in Spanish," set smaller, easy-to-reach goals. For example, try "learn 10 new Spanish words each day" or “listen to one Spanish podcast each week.” This makes your goal seem less overwhelming and helps you feel accomplished over time.

    that mixing big-picture goals with small, specific ones can be a useful way to stay on track when working toward long-term objectives.

    2. Use the power of routine

    Connect your new learning habit with one you already do. This is called “habit stacking.” For example, if you have coffee every morning, decide to study for 15 minutes as you finish your drink. Linking the new habit to a routine you already have makes it more likely to stick.

    3. Track your progress

    Keeping track of your learning helps motivate you and shows where you can improve. Whether you check off lessons in a language learning app like Mondly by app or write notes in a journal, seeing what you’ve accomplished keeps you interested.

    4. Build accountability

    Tell your friends, family, or study groups about your learning goals. When someone else knows your goal, it can help you stay on track. It’s even better to join a community of others who want to learn, like on social media or in online classes.

    People who do well often set clear, achievable goals and share them with friends for support.

    5. Reward yourself

    Small rewards can go a long way toward maintaining motivation. Celebrate milestones with meaningful perks, such as a favorite treat, an afternoon off, or buying yourself a book on the subject you're learning.

    6. Anticipate and plan for setbacks

    Life happens—sometimes work is stressful or things go wrong. Remember that missing a day or getting behind doesn’t mean you've failed. Keep going by recognizing challenges and getting back to your study plan with fresh motivation.

    7. Don’t fear failure

    Mistakes are part of progress. Every mispronounced word or awkward conversation is a step closer to fluency.

    8. Reassess and adjust goals

    If your language learning plan isn’t working, change it. If weekly goals seem too much, try monthly goals instead. The key is flexibility.

    The reward of resolutions

    Keeping resolutions can be tough, but the benefits are great. Picture yourself reading a book in your target language, traveling more easily, or making stronger friendships with people from different cultures. With determination and these tips, you can achieve your language learning goals.

    Start today -Whether it's January or June, it's never too late to set new goals. Draft a language learning plan, break it into small steps, and watch as each day brings you closer to your destination.
