Conjunctions exercise 1: join ideas clearly

A conjunction is easier to choose when you first identify the link between the ideas. Read the first clause and then the second clause. Decide whether the second clause adds a fact, disagrees with an expectation, offers a choice, gives a result, or explains a reason.

The library was quiet, so I could concentrate.

The library being quiet comes first. Being able to concentrate happens as a result.

I could concentrate because the library was quiet.

This sentence gives the same basic situation, but it begins with the result and then supplies the reason.

What relationship do you hear in The door was open, but nobody was inside?

It is a contrast. An open door may make you expect people inside, but the second clause gives a different result.

Use and when you want to add another person, thing, action, or full idea. The two parts do not need to be identical, but they should fit together as information you are placing side by side.

Rosa packed her laptop and her charger.

The sentence adds two things that Rosa packed.

Rosa packed her laptop, and she checked the train time.

Here and joins two full clauses. A comma helps the reader see where the first clause ends.

Which word joins two added actions: We cleaned the kitchen, and we washed the dishes or We cleaned the kitchen, because we washed the dishes?

Use and when both actions are simply part of the same report.

Use but when the second part is different from what the first part may lead you to expect. But can show a direct opposite, a limitation, or an unexpected result.

The instructions looked simple, but I needed help.

Simple instructions may suggest that help will not be needed. The second clause changes that expectation.

Ava likes swimming, but her brother prefers cycling.

The two people have different preferences, so but makes the contrast clear.

Choose the better connector: It was late, but the children were still awake or It was late, so the children were still awake?

Use but. Late at night often makes you expect children to be asleep, so still awake is a contrast.

Use or when a person can choose one option or when either option is possible. You will often see or in questions, offers, and simple instructions.

You can pay by card or cash.

Card and cash are two possible payment methods.

Should we meet on Tuesday or Wednesday?

The question asks the listener to choose between two days.

Which word fits a choice in a message: Call me or send a text?

Use or because the speaker gives two alternative ways to contact them.

Use so to show a result. The cause normally comes before so, and the action or situation that follows is the result. This word is useful when you are explaining a decision.

My phone battery was low, so I took my charger.

The low battery is the cause. Taking the charger is the response to that problem.

The road was blocked, so the driver chose another route.

The blocked road explains why the driver changed direction.

Which part is the result in The printer stopped working, so I used the one upstairs?

I used the one upstairs is the result. It happened because the first printer stopped working.

Use because when you want to explain why something happened or why someone made a choice. The reason can come after the main clause or before it. Keep the two ideas close together so the listener can follow the logic.

I left early because I had a dentist appointment.

The appointment is the reason for leaving early.

Because the lift was broken, we used the stairs.

The reason comes first in this version. The comma separates the opening reason from the main clause.

What question can because answer in I wore boots because the path was muddy?

It answers Why did you wear boots? The muddy path is the reason.
