Question about commas, independent vs dependent clauses, coordinating vs subordinating conjunctions.

Question

Should a comma be used in this sentence before the word "as?" His inventions benefited the country, as his name became synonymous with quality.

Answer 1

Yes, a comma should be used before the word "as" in the sentence:

1. "His inventions benefited the country, as his name became synonymous with quality."

Answer 2

In the sentence "His inventions benefited the country, as his name became synonymous with quality," the comma before "as" is correctly used.

Here’s why:

1. Introductory Clause: The phrase following the comma ("as his name became synonymous with quality") provides additional information that explains or elaborates on the preceding clause. This is an example of a causal clause introduced by "as," which explains the reason or cause for the benefit described in the main clause.

2. Clarity: Using the comma helps to clearly separate the two ideas, making the sentence easier to read and understand. It indicates a pause where the reader can grasp the connection between the two parts of the sentence.

Without the comma, the sentence might feel rushed or harder to parse, which could lead to confusion about how the two clauses relate. So, keeping the comma helps maintain clarity and readability.

Answer 3

In the context of your sentence, the comma should be used before the word as in order to emphasize the cause and effect relationship. So, the comma is necessary. As a general rule, however, you don't need a comma but it depends on the context of the sentence. Is there a cause and effect relationship in the sentence? That is something to think about when wondering whether to put a comma or not.

Let's look at the difference between an independent clause vs. a dependent clause. An independent clause is a sentence that can stands on its own and has a subject/noun and a verb (Example: I love to eat.) A dependent clause expresses an incomplete thought and needs the main sentence to support it (Example: I love to eat as I'm watching TV.)

Finally, let's learn the difference between coordinating vs. subordinating conjunctions. Coordinating conjunctions are words that connect two independent clauses. The most common coordinating conjunctions used are: for, and, nor, but, or, yet, and so. (Example: I like to read and write) A way to remember coordinating conjunctions is to use the acronym FANBOYS:

For

And

Nor

But

Or

Yet

So

A subordinating conjunction are words that introduce dependent clauses. (Example: When the time is right) The most commonly used subordinating conjunctions are because, although, if, when, as. There are many other examples of subordinating conjunctions such as whereas, whenever, while, after, and before. However, subordinating conjunctions can also be used to connect two clauses (Example: You need to eat your vegetables because it's healthy) By using a subordinating conjunction to connect two clauses, you are showing a cause and effect relationship.

Now, let's look at the sentence that you have and see if we can determine the independent/dependent clause and the coordinating/subordinating conjunction:

His inventions benefited the country, as his name became synonymous with quality.

His inventions benefited the country is an independent clause because we have a noun and a verb, therefore the sentence is complete and can stands on its own. If we read the rest of the sentence, the word as is a subordinating conjunction because it is used to introduce the dependent clause which is "as his name became synonymous with quality."
