Hi, again. Welcome back to www.engvid.com. I'm Adam. Today's lesson is -- actually, I
had a few requests for it. So I'm not going to mention names right now because there are
too many to mention. But some people asked me about transitions, again, specifically, "therefore"
and "thus". But I figured I would do the whole package because they can all work together.
If you're writing essays, you can use more than one of these, more than two of these,
especially for longer essays. So first, we're going to look at the differences or similarities
-- as the case may be -- of these words and when and how they are used. Okay?
So the words we're looking at today are "therefore", "thus", "consequently", "so", "then, "hence",
and the expression "as a result". Okay? So again, all of these are transitions. I'll
put it here.
So a little review. What is a transition? A transition is like a bridge that connects
two ideas. Okay? So what are we connecting here? What are the ideas that we want to connect?
We want to connect a logical conclusion. Okay? Or we want to connect a consequence. What
is a "consequence"? A consequence is, basically, a result. So for example, in life, we make
choices, we make decisions, and then, we have to live with the consequences, whatever those
choices bring us. Okay? So there's a very, very slight difference in these three words,
especially. These are the three that I want you to use most on essays if you're going
to be writing essays. Okay? We use "therefore" -- again, it's more of a mathematical word,
but we use it, obviously, to write, as well. When we have a premise, from there premise,
we generally reach a conclusion. Now, what is a "premise"? A "premise" is an idea that
we believe to be true. And because we believe it is true, from that truth we reach a conclusion.
Okay? I think everybody knows a very famous "premise + conclusion" sentence. "I think"
-- premise -- "I believe that I think, therefore I am." That's the conclusion I reach. Because
I think, I am. Okay. Don't be confused. It's not "because". Premise and conclusion, but
I'm just trying to simplify it a little bit.
"Thus" means "result". Now, it's a little bit different from "consequence". "Result"
means a result of the last argument. Okay? And "consequence" is -- again, it's a result,
but a consequence. Something's going to happen as a result of the thing before. Now, it's
very, very important to remember, something had to be mentioned before you can use any
of these words. Okay? All of these words and whatever sentence or clause or whatever comes
after it is in relation to what came before. Okay? I said something before; this is my
conclusion now. Or this is the result of what happened or this is the consequence.
More informally, we can use "so" also to talk about a consequence or a result. We use "then".
So, "This happened. Then, I did this." Not "then" like time, like sequence. "Then" means
more like, "This happened, so I did this." "This happened. Then, I did that as a result
of the first thing."
Now, a lot of people ask me about this word, "hence". The first thing I will say is don't
use it. One, it's a bit old-fashioned and a bit snobby. And two, most people don't use
it correctly anyway. I personally don't like this word, but if you must use it, then, remember
it's also like a consequence. Use it instead of "thus" -- probably instead of "therefore".
And of course, very casual, "as a result". Okay? So before we look at this -- all of
these individually, let's look at some examples. "I am cold." Okay? This is the situation.
"I am cold. Therefore, I'll put on a coat." [Coughs] Excuse me. Actually, you know what?
Let me change this. Sorry. I'll put a period here. If I were going to use "therefore" with
this, I would start a new sentence. All of these words can be used to start a sentence
or mid-sentence. But some of them are better used to start. Some of them are better used
in the middle. "I'm cold. Therefore, I'll put on a coat."
Now, if I'm grading your essay -- let's say you're writing IELTS or TOEFL, etc. -- and
you wrote "therefore, I'll put on a coat", I would actually take off points. Why? Because
you're trying to impress me. For something this casual, don't use "therefore"; use "so".
"I'm cold, so I'll put on a coat." This is the situation. This is what I'm going to do
as a result of the situation. "I'm cold" -- and then, I would put period. "Then, I'll put
on a coat." I've made a decision. "I'll put on a coat as a result of being cold." Don't
use "therefore". Don't use "thus". "Consequently" -- I won't take off points, but I won't give
you points either, okay? "Hence" -- don't do it. And "as a result" -- again, a little
bit too formal for this context. But let's look at a slightly more sophisticated context,
a little bit better-written sentence and see what the difference is.
Okay. So let's look at this sentence now. It's a little bit more formal. We're talking
about something a little bit more serious. We're going to look at the situation and the
result or the consequence, etc. "Sales shrank, and the competition was increasing its market
share." Okay? You're talking -- maybe this is a business article, or you're talking about
some sort of product, etc. So this is the situation. This is what is happening with
this product or this company. And they want to do something. So you can say, "Therefore"
-- you're starting the sentence, capital T, beginning of the sentence. "Therefore, the
company decided to invest more in R and D". Research and development. "Consequently" -- so
as a consequence of this situation -- "the company decided to invest." "Thus, the company
decided to invest." So all of these show that this is came about as a result of this situation.
Okay? That's one way.
You can also do it mid-sentence. Again, "Sales shrank, and the competition was increasing
its market share. The company therefore decided to invest..." Now, you could put -- actually,
I'll do it in purple. You could put commas here. Okay? And many people do that. The only
difference between with commas and without commas is pace. "The company, therefore, decided
to..." Without commas, "The company therefore decided to..." Okay? You want to emphasize
this or you want to emphasize the decision. Okay? It depends. "They drew this decision
as a conclusion." Okay? "Therefore decided." "The company decided" -- you can even take
this out. "The company decided to invest more." But you want to show the transition. You want
to show the direct link between the two sentences. So again, the commas, just for pace and what
you want to emphasize or not. "The company, consequently, decided to..." "The company
consequently decided to invest." "The company thus decided to invest." Okay?
"Thus" -- okay. I would not put commas. Don't put commas with "thus" because it slows it
down a little bit too much. "The company thus decide today invest." Okay? This is a bit
more of a direct link, so you can't put the commas to de-emphasize. It's a direct emphasis.
That's one.
Now, let's look at another way of doing this. "It was too expensive." Okay? Let's say we're
talking about same article. We're talking about research and development. They wanted
to invest more. But then, they realized that it was too expensive. So here, if I'm using
"so" -- remember; in an essay, if you've used "therefore", "thus", and "consequently" already,
you don't want to repeat many words. In this case, it's okay to use "so". Don't use "so"
casually. But if you've used the other ones too many times, you want variety. So you can
start using "so" as well. "It was too expensive, so they decide today do something else." "It
was too expensive." See here? Semicolon. I hope you can see that. "Consequently" is a
perfect word to use after a semicolon. "Consequently, it was too expensive." It's like a stop, but
it's not. But it's not a comma, either. "Consequently, they decided to do something else."
"It was too expensive, and thus..." So here, I'm using "thus" instead of the semicolon.
You could use "thus" after the semicolon as well. You could use "and so". Notice that
I'm not using "therefore". Okay? Because this is more of a consequence than it is a conclusion.
I'm not taking this to be a truth and because of this truth, I'm reaching a conclusion.
There's a consequence. So you see there's a slight -- very slight difference between
"therefore" and "thus" or "consequently". And if you can use the words correctly in
an essay, extra points for you, especially if I'm marking it because I like that. Okay?
Now, we're going to look at one more example, and then, we'll understand it a little bit better.
Okay. So let's look at the last example here -- actually, last couple of examples here.
I want you to also realize that you can use two of these transitions in one sentence or
in one situation. "The job was too demanding, so many people quit. Consequently, the company
hired new employees." So this "so" shows the connection between these two ideas within
one sentence. And then, the next sentence shows the consequence of the last sentence, okay?
So don't be afraid to mix them up. You can have more than one idea. One situation resulted
in another situation. Is this entire situation resulted in a whole other consequence, for
example, right?
And another thing I want to mention, "so" is used in many different ways. Be careful
that you're using the right form or the right function of "so". I could've written, "The
job was so demanding that many people quit." Okay? That's a little bit of a different form
of "so" because here, we're talking about modifying "demanding". And the "that" would
be the result part of it. Okay? I don't want to confuse you. I don't want to get into that.
Just understand "so" has many uses. Make sure you're using it correctly to join another
clause to another clause, and they have a logical consequence relationship. And then,
the next sentence begins with a clause relating again to the last sentence completely.
Now, one other thing. Some of you may be reading, and you may actually come across this, for
example, in TOEFL or IELTS, "thus". "Thus" is sometimes mean "like this" or "like that".
Okay? "If the model is thus constructed" -- so if the model is constructed this way or like
this, the result will vary, and we won't know what the real answer is. So be careful. "Thus"
has a completely different meaning. Again, a little bit old-fashioned. People don't really
use it very much anymore. But you may see it. Make sure you understand what it means.
And I didn't mention -- so far, I didn't mention "then". "It's too difficult." Person A says,
"It's too difficult." The person says, "Then practice more." This "then" means this is
the situation; this is what you should do, the result. I could say, "So practice more.
Then practice more." I will not say, "As a result of it being difficult, you should practice
more." Don't say that. Very, very casual. In very casual -- especially spoken -- situations,
you might want to use "then". Again, I could put "hence" here. But I don't want to. I don't
want you to, either. But if you insist on using "hence", you could put it here. It's
basically showing the relationship of situation, result. Okay?
