Comma With “Thus” – Rules, Examples & Practice Sheet

The correct use of commas in an academic paper is integral to remaining clear and structured while enabling an easier understanding. Because many students lack proper knowledge about comma rules, they often face difficulties with correctly using and applying them in academic writing. Consequently, this causes the emergence of impactful errors in sentence structure and meaning. This article aims to clarify the rules for using commas with “thus.”

When to place a comma with “thus”

To accurately apply commas with “thus,” understanding its meanings is crucial, as it typically references a preceding sentence element. “Thus” can function as a conjunctive adverb and translates to “consequently” or “therefore.” In this case, it works as a coordinating conjunction to connect two independent clauses, where it is preceded by a semicolon and followed by a comma. Essentially, a comma also follows “thus” when it introduces a sentence, however, this use is stylistic rather than obligatory. With the same meaning of “consequently,” when “thus” introduces a gerund or gerund phrase, it is typically preceded by a comma. Additionally, commas can bracket “thus” when it interrupts an independent clause, causing a pronounced pause.

Notably, “thus” is deemed formal and may not always require a comma, especially when it takes on the meaning of “in this way,” or is placed mid-sentence between compound verbs without necessitating a pause. The choice between using a comma for weak vs. strong breaks hinges on the desired emphasis or clarity, underscoring the nuanced role of “thus” in academic writing.

Comma rules may vary depending on different Style Guides. In general, it is to be considered whether the sentence is easily understood without the usage of a comma.

Comma with “thus”

A comma with “thus” is used if it introduces a sentence, functions as a conjunctive adverb between two independent clauses, introduces a gerund, or indicates a strong break in a formal register.

Functions as a conjunctive adverb

A comma with “thus” is used when it functions as a conjunctive adverb, placed between two independent clauses. A conjunctive adverb is a coordinating conjunction like “and” or “but” and aims to join two independent clauses. In this case, the first independent clause is concluded with a semicolon to separate the two independent clauses and followed by “thus,” acting as the link between the two clauses. A comma follows “thus” to clarify the separation. By using a comma and a semicolon in the process, you create a cause-and-effect relationship between the two independent sentences and enhance clarity.

Introduces a sentence

When “thus” is placed at the beginning of a sentence to introduce it, a comma follows “thus,” as it takes on the function of an adverb, modifying elements of or the entire sentence. There is no strict punctuation rule, therefore, we advise you to follow the specifics of the Style Guide you chose to follow. Generally, it is recommended to place a comma for clarity.

Introduces a gerund

A comma with “thus” is typically used when it introduces a gerund or gerund phrase. When “thus” translates to the meaning of “thereby” or “consequently,” a comma before the word is necessary to indicate the separation between the previous sentence element and the link between “thus” and the gerund.

Causes a pronounced pause

In sentence structure, you can distinguish between “strong” and “weak” breaks referring to the stress and emphasis put on different words or elements in a sentence. Differentiating between these types of breaks plays a vital role due to their ability to change the delivery and meaning of a sentence. When “thus” functions as a pronounced pause, it provides a great emphasis to the flow of the whole sentence. When this can be categorized as a proper interruption, commas are needed around “thus.”

No comma with “thus”

You don’t need to use a comma with “thus” when it conveys the meaning of “like this” or “in this way.” Another case where a comma is not necessary is when it appears between compound verbs or merely causes a weak break within a sentence.

Translates to “in this way”

When “thus” can be used as a synonym for “like this” or “in this way,” comma around “thus” should be omitted.

Placed between compound verbs

Compound verbs consist of multiple words, creating a verb with a single meaning. When “thus” is placed between compound verbs, it serves to connect or modify the actions described by those verbs, often indicating the manner or consequence of the actions without the need for a comma.

Causes a weak pause

As previously explained, there is a stress and emphasis related distinction between a strong vs. a weak break in a sentence. When “thus” causes a weak break, meaning that it does not emphasize a certain meaning, a comma is not required.
