Conjunctions: The Linking Words of English Grammar

A Conjunction is a word used to connect words, phrases, clauses, or sentences. They are the “glue” that holds ideas together in a sentence.

1. Coordinating Conjunctions (FANBOYS)

These join words, phrases, or independent clauses of equal rank. Remember the acronym FANBOYS.

Conjunction Function Example
For Reason (similar to ‘because’) He went to bed early, for he was tired.
And Addition She bought a book and a pen.
Nor Negative alternative He doesn’t like tea, nor does he like coffee.
But Contrast She is small but strong.
Or Choice Would you like tea or coffee?
Yet Contrast (stronger than ‘but’) He worked hard, yet he failed.
So Result/Consequence It was raining, so we stayed home.

2. Subordinating Conjunctions

These join a dependent (subordinate) clause to an independent (main) clause. They show a relationship like time, cause, condition, or contrast.

Category Conjunctions Example
Time when, while, after, before, until, since, as soon as When the bell rings, the class will end.
Cause & Effect because, since, as, so that He failed because he didn’t study.
Condition if, unless, provided that, as long as You will pass if you work hard.
Contrast although, though, even though, whereas Although it was raining, we went out.
Purpose so that, in order that He saved money so that he could buy a car.

3. Correlative Conjunctions

These are used in pairs to connect equal grammatical elements.

Pair Example
either…or You can have either tea or coffee.
neither…nor Neither John nor Sam attended the meeting.
both…and She is both intelligent and hardworking.
not only…but also He is not only a singer but also a dancer.
whether…or I can’t decide whether to go or stay.

Common Errors 

Error 1: Double Conjunctions

Avoid using two conjunctions for the same clause.

  • Incorrect: Though he was poor but he was honest.
  • Correct: Though he was poor, he was honest. OR He was poor but he was honest.

Error 2: “Until” vs “Unless”

  • Until is used for time. (Wait until I come.)
  • Unless is used for condition. (You will fail unless you study.)

Error 3: “Since” vs “For”

  • Since is used with a point of time. (I have lived here since 2010.)
  • For is used with a period of time. (I have lived here for ten years.)

Error 4: “So…that” vs “Such…that”

  • So + Adjective/Adverb + that: He is so weak that he cannot walk.
  • Such + (a/an) + Adjective + Noun + that: It was such a hot day that we stayed indoors.

Error 5: “Lest”

“Lest” means “for fear that” and is followed by “should”.

  • Example: Work hard lest you should fail.
