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".

    Writing your own English language materials with the GSE

    By Billie Jago

    Being an English language teacher means you’re also probably (definitely) a materials writer. You likely tailor or create language materials for your students that are suited to their needs and interests, either as supplements to your course materials or for communicative lessons. Alternatively, you might be a teacher who creates paid, published materials available for students worldwide to enjoy.

    With this in mind, think of the materials you’ve developed and ask yourself the following:

    • How do you level your grammar or vocabulary for the content you write?
    • How do you find topic-related vocabulary to extend your students’ knowledge of language?
    • How do you contextualize new grammar or vocabulary?

    You can use many different resources, from online dictionaries to course workbooks to a Google search. Still, the Global Scale of English is a reference that provides everything you need to write great learning materials, all in one place. It can help save you valuable time as a teacher and materials writer.

    For me, the GSE was a game changer as an English teacher, and it continues to be as I write materials. The GSE is not just a tool; it’s a companion in the complex journey of material development, offering clarity and direction at every step. It can guide you in creating effective, engaging learning resources.

    How to use the GSE toolkit to create your own materials

    1. Establishing clear Learning Objectives

    helps you start with a clear roadmap. It provides detailed descriptors for language proficiency at every level, ensuring your materials align with specific learning objectives. For instance, if you’re creating a beginner-level reading comprehension activity, the GSE descriptors will guide you on the appropriate complexity of vocabulary and sentence structures.

    Take a look at the Learning Objectives tab in the GSE Toolkit to learn more.

    2. Designing level-appropriate content

    Once objectives are set, the GSE assists in tailoring the content difficulty to the targeted proficiency level. Its numerical scale, ranging from 10 to 90, allows you to pinpoint the exact level of language skills required and design your materials accordingly. This precision ensures that learners are neither overwhelmed nor under-challenged.

    You can set the level you are looking for by sliding the bar along the scale, so it corresponds to the appropriate CEFR level or GSE range.
