PE-52: Conjunctions: and, but, or, so, because
The words that join ideas into real sentences — and the although/but mistake that comes straight from Uzbek.
PE-52: Conjunctions: and, but, or, so, because
"I was tired. I went home. I slept." Every sentence is correct — and it reads like a five-year-old wrote it. Real English joins ideas together: "I was tired, so I went home and slept." The words that do this joining are called conjunctions, and they are the first tool of Block E: building bigger sentences.
In this lesson you will learn
- The five everyday joiners: and, but, or, so, because
- Why so and because point in opposite directions
- although — and why you must never add but after it
- Where the comma goes
1. The five you need every day
1and — adding
I bought bread and milk.
2but — contrast
It's cheap but good.
3or — choice
Tea or coffee?
4so — result
It was late, so I left.
5because — reason
I left because it was late.
6although — contrast
Although it rained, we went.
Afsona studies hard and she helps at home, but she never complains.
Afsona qattiq oʻqiydi va uyda yordam beradi, lekin hech qachon shikoyat qilmaydi.
2. so and because — the same idea, opposite order
This pair confuses many learners, but the logic is simple. Because introduces the reason. So introduces the result. The same two facts can be joined either way — you just swap their order.
because + reason
I went home because I was tired.
result ← reason
so + result
I was tired, so I went home.
reason → result
Also note because + a full clause vs because of + a noun:
We stayed at home because it rained. = We stayed at home because of the rain.
Yomgʻir yogʻgani uchun uyda qoldik. = Yomgʻir tufayli uyda qoldik.
because needs a subject and a verb; because of needs only a noun.
3. although — and the mistake that comes from Uzbek
In Uzbek, a contrast sentence takes two markers: Garchi charchagan boʻlsam ham, lekin ishladim. English uses only one. Writing both is one of the most recognisable Uzbek-speaker errors in written English.
Although it was raining, but we went out.
Although it was raining, we went out.
It was raining, but we went out.
Though means the same as although and is more common in speech; even though is stronger. All three follow the same one-joiner rule.
4. Where the comma goes
- Before but and so when they join two full sentences: It was cold, so we stayed in.
- No comma before because in a short sentence: I stayed in because it was cold.
- Comma when the joined part comes first: Although it was cold, we went out.
- No comma when joining two short words or phrases: bread and milk.
When the lesson finished, we went home. — We went home when the lesson finished.
Dars tugagach, uyga ketdik. — Dars tugagach uyga ketdik.
The comma appears only in the first version, where the clause comes first.
5. Common mistakes
Because I was ill, so I didn't come.
Because I was ill, I didn't come. / I was ill, so I didn't come.
We stayed home because of it rained.
We stayed home because it rained / because of the rain.
Although he is rich, but he isn't happy.
Although he is rich, he isn't happy.
I like tea and I don't like coffee.
I like tea but I don't like coffee. (contrast, not addition)
He was tired so much that he slept.
He was so tired that he slept.
Practice
1 Join with so and then with because: It was very hot. We stayed inside.
Show answer
It was very hot, so we stayed inside.
We stayed inside because it was very hot.
Same meaning — the order of reason and result simply swaps.
2 Correct it: Although Jasur studied hard, but he failed the test.
Show answer
Although Jasur studied hard, he failed the test.
One joiner only. (Oʻzbekcha: "garchi...lekin" ingliz tilida ikkitasi boʻlmaydi.)
3 because or because of: The match was cancelled ___ the bad weather.
Show answer
because of — the bad weather is a noun phrase, with no verb. With a verb you would say because the weather was bad.
4 Where does the comma go? When I got home my mother was cooking.
Show answer
When I got home, my mother was cooking.
The clause comes first, so a comma separates the two halves.
5 Join these three short sentences into one: I was hungry. There was no bread. I made eggs.
Show answer
Model: I was hungry, but there was no bread, so I made eggs.
Three ideas, one sentence, two different joiners — that is adult English.

🎯 Remember this
- and adds · but contrasts · or chooses · so gives the result · because gives the reason.
- because + reason · so + result — never both in one sentence.
- because + subject + verb · because of + noun.
- Although …
but— English uses one joiner, not two. - Comma when the joined clause comes first.
