1. What Are Conjunctions?

Definition

Conjunctions are words used to connect words, phrases, or clauses in a sentence. They act as bridges, allowing ideas to flow smoothly and logically.

Types of Conjunctions

1. Coordinating Conjunctions: Connect two equal parts of a sentence (e.g., and, but, or).

2. Subordinating Conjunctions: Link a dependent clause to an independent clause (e.g., because, although, since).

3. Correlative Conjunctions: Work in pairs to join elements (e.g., either…or, neither…nor).

Rules for Using Conjunctions

• • Ensure the conjunction fits the context of the sentence.
  • Avoid overusing conjunctions, as it can make sentences lengthy and confusing.
  • Maintain parallel structure when using conjunctions.

2. Common Conjunctions and Examples

Coordinating Conjunctions

These conjunctions connect words, phrases, or clauses of equal importance.

Examples:

• • And: Combines similar ideas.
    • She loves painting and drawing.
  • But: Contrasts ideas.
    • He wanted to go to the party, but he was too tired.
  • Or: Presents alternatives.
    • Would you like tea or coffee?

Subordinating Conjunctions

These introduce a subordinate clause, explaining why, when, or how something happened.

Examples:

• • Because: Indicates reason.

  • Although: Indicates contrast.
    • Although he was tired, he continued working.
  • Since: Indicates time or reason.
    • He has been happy since he got a new job.

Correlative Conjunctions

These conjunction pairs ensure balance and clarity.

Examples:

• • Either…or: Presents choices.
    • You can either walk or take the bus.
  • Neither…nor: Presents negative choices.
    • She likes neither tea nor coffee.
