The word ‘so’
Welcome to today’s Lunchtime Lesson. Today’s focus is on the word so. I’ve chosen the word so because I’ve noticed that a lot of students can’t use it correctly. The reason for that is that there are different functions for the word so and also lots of expressions. And on top of that the pronunciation that we use with it depends on which function we are using. No wonder so many students struggle with it and aren’t sure about how to use it. But if you think about it, you will probably notice how often I use the word so in my lessons. It must be at least a million times. So, yes, it’s really a very common word and we use it all the time.
The main ways to use so in terms of functions is as a modifier, as a linker and as a discourse marker. If you’re not sure what those mean, don’t worry, I’m going to give you examples for each of them.
‘So’ as a modifier
Starting with so as a modifier. That means we use the word so with an adjective or with much or many and a noun to modify the adjectives and to modify the nouns. As an example, you can use so in the same way as very. Something is so beautiful or something is very beautiful. Both have the same function.
To give you some more examples:
– The film was so boring that I fell asleep.
What I’m doing is I’m modifying the word boring to make it more intense.
– He has so much money, he can buy anything.
And again, by using so much or so many, we are intensifying the noun.
But please be careful when you use so as a modifier. What do you think, how strong is so as a modifier? On a scale you can think about quite being like 50% and absolutely being 100%. Where would you place so?

So’s intensity is often misunderstood. It’s a really strong modifier and it’s closer to absolutely than very. What happens is that we often use so incorrectly as we think it’s not such a strong modifier as it actually is.
The other important thing when we’re using so as a modifier is the pronunciation. As it is a strong modifier your voice and your intonation have to reflect that. What happens if I don’t emphasize the so? How do I sound? I sound sarcastic. And that can actually be quite rude, and you might find yourself in a rather embarrassing situation. So, if you’re speaking to somebody, we need to make sure, like with any strong modifier, that our voice is reflecting it. You need to make it quite long and make sure that you’re emphasizing it when you’re using it this way. Best way to practice this, is to watch the video and repeat after Claire.
‘So’ as a linker
Another common way we use so is as a linker. A linker is a word that connects sentences. With so there are two different uses. The first one is to show a result or effect. For example, I was tired and as a result of me being tired I went to bed. I was tired, so I went to bed. If you wanted to use another linker, the word consequently would work. I was tired, consequently I went to bed. Both express the same.
The other way that we can use so as linker, is to talk about reason or to express an intention. For example, I moved to London so that I can be closer to my family. Why did I move to London? To be closer to my family. The register of this is neutral to informal. And we when we’re using so, we need to follow this pattern:
So (that) + can/ could or will/would
I’m moving to London so (that) I will/would/can/could be closer to my family.
We don’t need to use that, but we always need to use a model verb!
When we use so as a linker, we pronounce it differently to when we use it as a modifier. We don’t stress it like we did when it’s functioning as a modifier. We say it in a much softer way. That’s a mistake I have noticed sometimes with students. They are using so correctly grammatically but because they’re using the wrong intonation, the sentence sounds wrong.
In terms of exams, for example, these are things which are very important as the wrong intonation will be a mistake even though you might have used so correctly in a grammatical sense. So be very careful about it.
‘So’ as a discourse marker
The last function we’re going to think about is so as a discourse marker. A discourse marker is a word that we use to organize our speech. It doesn’t necessarily have any specific meaning, but it gives important information to the listener. Words like this exist in all languages, in Spanish for example it’s the word bueno or in German also. Those words don’t actually giving any important information in terms of the message you’re communicating, but they’re giving the listener important information about what you are going to do with your language. We use so as a discourse marker at the start of sentences to introduce information. If you watch the video, you’ll see that Claire uses so in this way all the time.
So, today we’re going to talk about modifiers.
So, what do you think about the Olympics?
In these sentences, so is used to introduce what I’m going to talk about. When we use so as a discourse marker to introduce information, we very often reply to it with the word well.
As an example:
So, what do you think about the Olympics? Well, to be honest, I think they’re a terrible idea.
So, this is another really common use of the word so and again, the intonation and the pronunciation are different. If I’m using it as a discourse marker, the intonation is higher. To illustrate that for you, it would look like the green line in the example sentence on the right.
To practise this, watch the video and repeat after Claire. If you don’t use the correct intonation, the meaning changes and the listener will most likely be confused. Long story short, intonation is so much more important than we think it is.
Useful expressions with ‘so’
Apart from these different functions, so is also part of many expressions. Can you match the expression to their meanings? Take a couple of minutes and try to match them.

This are some really nice and useful expressions which you can use in your everyday life. If you’re thinking of taking an exam, these expressions are brilliant. If you use them in your speaking and writing the examiner will be impressed.
As a challenge for this week, try some of these expressions in your daily life. Maybe even leave us a comment with one of the expressions you just learned.
