Coordinating conjunctions

A1 Beginner

Coordinating conjunctions connect words, phrases, or independent clauses of equal grammatical importance. The most common forms at A1 level are and, but, or, and so.

Overview

Coordinating conjunctions function as links between elements that have the same status in a sentence. They can join two nouns, two verbs, or two complete sentences to show a specific relationship between them.

And adds information.
But shows a contrast or a different idea.
Or presents a choice or alternative.
So shows a result or consequence.

Sentence Structure

Clause 1 + , + conjunction + Clause 2

When joining two independent clauses (complete sentences), a comma is typically placed before the conjunction. When joining two words or short phrases, no comma is required.

Examples

Common mistakes

I am hungry, because I eat a sandwich.
I am hungry, so I eat a sandwich.
Use 'so' for the result. 'Because' is used for the reason, which would reverse the sentence order.
She speaks English but Spanish.
She speaks English and Spanish.
Use 'and' to add similar items. 'But' is only for contrasting or opposite ideas.
