I'm having a hard time understanding the difference among a subordinating conjunction, a correlative conjunction, and a coordinating conjunction.

Thank you!
Thank you!

The differences are explained in great detail, with examples, at

I confess I have not read it all, and would probably not remember the diffrent definitions if I did. Perhaps one of our English experts can give a more concise definition.

Coordinating conjunctions (FANBOYS) join equal things -- that is, are used to join two independent clauses (making a compound sentence), to join two subjects (making a compound subject), etc. Correlative conjunctions do about the same thing as coordinating conjunctions, but they always appear in pairs.

Subordinating conjunctions are used to join two unequal things -- that is, an independent clause with a dependent clause or an independent clause with a phrase.

There's a good section at the beginning of this webpage explaining the coordinating conjunctions and what each is used for. Subordinating conjunctions are after that, and the section on correlative conjunctions is near the bottom.

subordinating conjunction =

the subordination that occurs when a conjunction makes one linguistic unit a constituent of another
a conjunction (like `since' or `that' or `who') that introduces a dependent clause

correlative conjunction =
In grammar, a conjunction is a part of speech that connects two words, phrases or clauses together

coordinating conjunction =
the coordination by conjunction of linguistic units of the same status
a conjunction (like `and' or `or') that connects two identically constructed grammatical constituents.

In grammar, a conjunction is a part of speech that connects two words, phrases or clauses together. This definition may overlap with that of other parts of speech, so what constitutes a "conjunction"

Sure! I'd be happy to help you understand the difference between these types of conjunctions.

1. Subordinating Conjunction:
A subordinating conjunction is a word that joins two clauses or ideas and shows the relationship between them. It introduces a subordinate clause, which cannot stand alone as a complete sentence. Examples of subordinating conjunctions include "because," "although," "while," "until," and "unless." To identify a subordinating conjunction, you can look for words that indicate time, cause and effect, contrast, or condition.

To understand the concept further, you can start by identifying two independent clauses (sentences that can stand by themselves) and connecting them with a subordinating conjunction. Then, analyze the relationship between the clauses that the conjunction creates. For example:
- "I bought an umbrella because it was raining."
Here, "because" is the subordinating conjunction that shows the cause and effect relationship between "I bought an umbrella" and "it was raining."

2. Correlative Conjunction:
Correlative conjunctions are pairs of words that work together to connect equal parts of a sentence. They show a relationship between two ideas or elements, such as words, phrases, or clauses. Common examples of correlative conjunctions include "both...and," "either...or," "neither...nor," "not only...but also," and "whether...or."

To understand how to identify and use correlative conjunctions, you can start by identifying two related words or elements in a sentence and use a suitable correlative conjunction to join them. For example:
- "You can either watch a movie at home or go to the cinema."
Here, "either" and "or" are the correlative conjunctions that connect the choices of watching a movie at home or going to the cinema.

3. Coordinating Conjunction:
A coordinating conjunction is a word that connects two words, phrases, or independent clauses of equal importance within a sentence. It shows a relationship of equal importance, addition, contrast, or choice between the connected elements. Common examples of coordinating conjunctions include "and," "but," "or," "so," "nor," and "for."

To understand how to identify and use coordinating conjunctions, you can start by identifying two elements in a sentence that are equal in importance and connect them using a coordinating conjunction. For example:
- "I like watching movies, but my brother prefers reading books."
Here, "but" is the coordinating conjunction that connects the two independent clauses showing a contrast in preferences between watching movies and reading books.

To summarize, subordinating conjunctions connect dependent clauses to independent clauses, correlative conjunctions connect equal parts of a sentence, and coordinating conjunctions connect equal elements within a sentence. Practice identifying and using these different types of conjunctions in various sentences to strengthen your understanding.
