1. Understanding Conjunctions

A conjunction is a word that “joins” words, phrases, or clauses in a sentence to send a logical message. It literally connects parts of a sentence together. Conjunctions help us combine short, choppy sentences into longer, smoother ones.

Coordinating Conjunctions

These join ideas of equal importance. You can remember them with the acronym FANBOYS:

For (reason)
And (addition/sequence)
Nor (negative addition)
But (contrast)
Or (choice)
Yet (contrast/surprise)
So (result)

Example: Rafael is an excellent defender, so he made the team.

Subordinating Conjunctions

These words join a dependent clause (a group of words that cannot stand alone) to an independent clause (a complete thought). They often tell when, where, why, or how.

Common Subordinators: after, although, because, before, if, since, so that, unless, until, when, while.

Example: Although Rafael’s mother was worried, she let him play.

Exercise 1: Identifying Conjunctions

Circle the conjunction in each sentence below.

Rafael wanted to join the team, but his mother thought it was dangerous.
He borrowed a uniform so his mother could see the protective gear.
They knew it could change her mind or convince her she was right.
Rafael and his dad convinced his mother to go to a practice.
The coaches supervised them well, yet she was still worried.
She said he could join since he promised to be careful.
Rafael didn’t know whether to jump for joy or nod seriously.
Rafael’s mother and father went to every game.

Exercise 2: Coordinate or Subordinate?

Read the sentences. Identify if the underlined conjunction is Coordinating (C) or Subordinating (S).

I want to finish my homework, but I’d rather go to the mall. ______
Whether we go to the fair or stay home depends on the rain. ______
You can go if you finish your homework in time. ______
I was late because I overslept. ______
Kevin heard the weather report and packed his gear. ______
We left as soon as the concert ended. ______
Do not eat the bananas before they are ripe. ______
The story is unbelievable, yet supposedly true. ______

Exercise 3: Choosing the Right Word

Select the correct conjunction to complete the sentence.

The ducklings are brown, (but / or) the adult ducks are white.
We brought bread with us, (so / because) we fed the ducks.
The ducks might have gone to a nest, (and / or) they could have swum to shore.
(Although / Or) television prices seem high, they have hardly risen.
I cooked dinner (while / unless) she set the table.

(Since / But) you weren’t here yesterday, we presented without you.

Exercise 5: Sentence Combining

Combine the pair of sentences into one using the conjunction in parentheses.
