WHAT ARE CONJUNCTIONS?
Visit Merriam-Webster.com
Conjunctions are words that link clauses, phrases, or words in a list. These include: AND, OR, BUT, UNTIL, SINCE, EITHER, and OR. [Note: THEN is not a conjunction.]
A coordinate conjunction links clauses and phrases. Examples:
The campfire crackled, popped, and spewed sparks.
The campfire blazed but did not spew sparks.
The campfire could sizzle or spew sparks.
A coordinate conjunction can be used to link two related sentences. Examples:
The campfire blazed. But it did not spew sparks.
The campfire crackled. And then it spewed sparks.
A subordinate conjunction joins a subordinate clause to a main clause. Examples:
The campfire spewed sparks until the coals were stirred.
The campfire sizzled after grease was poured on it.
