Definition

1. Noun (Grammar):
   • A type of conjunction that connects words, phrases, or clauses of equal grammatical rank (e.g., two independent clauses, two nouns, two adjectives). The primary coordinating conjunctions in English are for, and, nor, but, or, yet, and so, often remembered by the acronym FANBOYS.
   • The grammatical function of linking linguistic units that share the same syntactic status within a sentence.

Usage

• A coordinating conjunction is used to join elements that are grammatically similar. It typically appears between the items it connects.
• When connecting two independent clauses, a comma is usually placed before the coordinating conjunction.

Examples

• Connecting words: "bread butter"
• Connecting phrases: "over the river through the woods"
• Connecting independent clauses: "She wanted to go for a walk, it started to rain."

Advanced Usage

• Punctuation with Independent Clauses: When a coordinating conjunction joins two independent clauses, it is often preceded by a comma.
  • Example: "I finished my work, so I decided to take a break."
• Serial Comma (Oxford Comma): In a list of three or more items, coordinating conjunctions (typically 'and' or 'or') are used before the final item. The use of a comma before this final conjunction is a matter of style.
  • Example: "The flag is red, white, and blue."

Variants and Related Words

• Conjunction (n): A broader word class for any word that connects clauses, sentences, words, or phrases. A coordinating conjunction is a specific subtype.
• Subordinating Conjunction (n): A conjunction that introduces a dependent clause, connecting it to an independent clause (e.g., , , ). This contrasts with a coordinating conjunction.
• Correlative Conjunction (n): Pairs of conjunctions that work together to link elements (e.g., , ). These are related to but distinct from single coordinating conjunctions.

Synonyms

• Coordinator (n): A less common technical synonym for a coordinating conjunction.

Related Phrases / Concepts

• Compound Sentence: A sentence containing at least two independent clauses joined by a coordinating conjunction.
  • Example: "The sun was shining, and the birds were singing."
• Parallel Structure: The use of a coordinating conjunction often requires the connected elements to be parallel in form (e.g., both nouns, both verb phrases).
  • Example (Correct Parallelism): "She likes hiking, swimming, and cycling." (All gerunds)
  • Example (Faulty Parallelism): "She likes hiking, to swim, and cycling." (Mixed forms)
