Unit 11.2

Conjunctions: And, But, Because, When



Conjunctions are words that function as a link between different clauses or elements in sentence.


Conjunctions are words that connect words, phrases and clauses in a sentence.
The main conjunctions are: and, but, because and when.

The structure of the sentence is:
Clause 1 + conjunctions + clause 2

If the sentence is longer we put comma (,) before the conjunction.


  • Kevin reads the newspaper and watches television every Friday.
  • They live in New York and love its beautiful library.
  • I like maths lessons but I don’t really like history lessons.
  • You can go hiking there but you have to be very careful.
  • Anna doesn’t want to take the exam because she did not study.
  • We can’t come to the party tonight because we must study.
  • You get very tired when you don’t sleep.
  • We came from school when nobody was home.


Conjunctions are used to connect words, phrases, clauses and sentences and show relations between them.

We can combine the clauses in different ways:

  • and: it connects two sentences (addition);
  • but: it states either a condition or a contrast (contrast);
  • because: it states the reason (cause);
  • when: it states the time of the sentences (time).


Conjunctions act as a link between words, phrases, clauses and sentence.

The main conjunctions are: and, but, because and when. The conjuctions are used between clauses.

For example:
— “I need to go to the supermarket and I also want to visit my grandmother.” = And is used to connect two sentences.
— “I need to go to the supermarket but I have to work.” = But is used to express an action that is in contrast with another action at the same time.
— “I need to go to the supermarket because we have no bread.” = Because is used to link the two parts of the sentence: the action and the cause of the action.
— “I need to go to the supermarket when I finish work.” = When is used to express the new action after the first one is already finished.
