With a comma. Always. Other than when friend don’t. Perhaps I have to annotate that: In the overwhelming majority of cases, monitor an introductory expression at the start of a sentence with a comma.

You are watching: Is there a comma after then

Adverbial ConjunctionsEight great of adverbial conjunctions exist, and also a comma should generally follow one in every class. Every of this sentences includes an instance of one such component of decided from every class:

Addition: “Finally, I got to the station.”

Comparison: “Similarly, chickens are omnivores.”

Concession: “Naturally, you’ll desire to see for yourself.”

(Note, however, the however isn’t always an adverbial conjunction. In this sentence, the an adverb editing and enhancing important: “However important you think the is, i’m not offering him the blog post right now.”)

Contrast: “Nevertheless, he didn’t enter detail.”

Emphasis: “Of course, she’ll be there, too.”

(An exception can be produced this particular phrase: yes sir a subtle however distinct difference between “Of course, you’ll want to do it your way” and also “Of food you’ll desire to perform it your way.” In the first sentence, your is stressed; in the second, course, probably accompanied through a sneer, is emphasized, with a secondary stress on your — and also likely an exclamation point to signal emotion.)

Example: “For instance, the floor was swept yet not mopped.”

Summary: “In conclusion, ns recommend the we provide the measure.”

Time sequence: “At last, we witnessed their auto approaching.”

(Some writing and also editing guides imply that brief introductory phrases don’t require commas; often, such short modifying unit volume involve time: “Yesterday I observed a ghost,” because that example, or “In 1492 Columbus sailed the s blue.” i recommend, though, use of commas in together cases. Otherwise, the exception to the rule is quite arbitrary; just how long does a short phrase have to be prior to it merits a comma? and also why omit commas in some cases and also include others?)

Hence, Still, Then, and also ThusAnother course of words may or may not be complied with by a comma relying on subtle differences:

“Hence the name,” however “Hence, i was back where I had started.”

“Still the waters raged despite the rain had actually ceased,” but “Still, I try one more time.”

“Then ns tried to start the auto again,” but “Then, i would have actually acted differently.”

“Thus us are earlier where us started,” but “Thus, i concede the point.”

Infinitive Phrases“To obtain there, turn appropriate at the second intersection.”

Participial Phrases“Under the circumstances, i cannot permit it.”

How have the right to you please explain the difference in between these two?

“Thus we are ago where we started,” yet “Thus, ns concede the point.”


Dayfon July 04, 2011 2:02 pm

Can friend please describe the difference between these two?“Thus us are back where we started,” but “Thus, ns concede the point.”Thanks.

Oh, heck, I’d never ever heard that an adverbial conjunction before, and also I don’t think I typically follow them with commas. Bummer. This is gonna take it a tiny mulling over.

Mark Nicholon July 04, 2011 10:06 pm


Good question. On more reflection, I would punctuate after for this reason in the first example, too. A far better example the a sentence in i m sorry no comma need to follow for this reason is the translate into of “Sic semper tyrannis” (“Thus always to tyrants”), wherein thus, despite an adverb, appears to act choose a pronoun — “This is what wake up to tyrants.”

Very interesting.

I teach my students that “if omitting a comma does no violate the sense, then omit it.”

Thus us would avoid what one of my teachers referred to as ‘tadpole-itis,’ a swarm the commas infesting the page.

I concur.

Isn’t a comma the typographical calculation of a pause as soon as speaking? for this reason a comma should be placed whenever you host your breath?

Oliver Lawrenceon July 09, 2011 8:05 am

Thanks, I took pleasure in reading her article.

There’s also the category of cause and result, such as “accordingly”, “as a result”, etc.

BTW, “Under the circumstances” is a prepositional phrase, no a participial one.

And I believe these points are much more commonly referred to as “conjunctive adverbs”, together in terms of word classes/parts the speech, strictly speaking they space adverbs (or adverb phrases), not conjunctions (see ‘Writing through Style’, Oxford 2010, and also and compare Ghit counts because that the two phrases).

Oliver Lawrenceon July 17, 2011 5:06 am

The special situations you raise wherein a comma is not forced or is optional are an especially interesting.In the situation of conjunctive adverbs not being supplied as one introductory expression (eg “however vital it might be, don’t do it – where “however” is not an introductory phrase yet “however important it may be” is; and “hence the name”), the general rule around using commas through introductory phrases remains intact.And for introductory phrases involving time, a good rule of thumb for as soon as the comma can/should it is in omitted is to take into consideration whether you would certainly make even the slightest pause once you speak the phrase: if not, a comma can safely be omitted. Less confident writers deserve to simply use the comma all the time and also they will certainly not be wrong.

“Of course, you’ll desire to carry out it her way”“Of course you’ll desire to do it her way.”In the first sentence, her is stressed; in the second, course, perhaps accompanied by a sneer, is emphasized, with a secondary stress on her — and likely an exclamation suggest to signal emotion.

If what ns learned around punctuation is correct, comma signifies a pause, and whichever complies with is emphasized. But according come what friend said, is what ns learned wrong? Thanks.

Tom and Amanda:

Although many civilization don’t consider a comma as a stop marker a technically valid role, it regularly serves that purpose. (But not everybody pauses in the very same place.)

Teahon September 09, 2012 9:57 pm

Sally and also Frank,If friend teach your students that “if omitting a comma does no violate the sense, then omit it.” You room teaching your students come punctuate incorrectly. The rule are just meant to be broken after you recognize them.Commas beat a crucial role in sentence structure.

Robert Traynoron December 11, 2015 3:05 am

The whole purpose of dot is to avoid a misreading the what is written and also to emphasize particular parts that what is written. If ns were to omit the comma in the following sentence, would the definition of the sentence be shed or changed?

Finally, he gotten in the room.

With or without the comma, the an interpretation of the sentence stays the same. As such the comma has actually a completely stylistic purpose. This means you can add it if you wish to emphasize “finally,” or you have the right to omit it. I would carry out the latter.

The existing trend is to reduce the variety of commas in your writing, which i think is a very sensible trend. Misreadings excepted, over there is no practical (as opposed to stylistic) worth to place commas after introduce words such as “naturally,” “ironically,” and “unfortunately” and also introductory unit volume such as “early in the morning.”
