When you start a sentence with one of those/these words, is there a comma needed after them?
After, soon, yesterday, tomorrow, last week, next week, and so on.
?
The particular words you’ve listed usually do not require a comma. A comma at the beginning of a sentence is intended to signal a pause, or a separation of the idea of the sentence from that part that precedes it. Usually this is limited to words like And, But, However, Thus, Hence, and Therefore. The usage is usually meant to connect a new sentence to an idea that is related, but somewhat separate from the previous sentence.
Otherwise, introductory phrases generally do not require a comma unless they are 4 word long or longer.
I hope that helps (and I love the screenname)!
Thank you so much for the answer!
It’s confusing because I sometimes see sentences like this,
Yesterday, my wife cooked the meal, and I did the dishes.
Yesterday, I did my homework and then watched some TV.
(Thank you, I’m glad you like my screenname : ) )
As I know, if your sentence begins with a time clause, you need to add comma behind.
I’m kind of obsessed with comma’s.
Is this a good sentence?
Next week, I have an appointment with my doctor.
I believe there are different schools among grammarians: some say you should, others say you shouldn’t use this comma with short adverbial constituents. Others consider it rather a matter of style than of grammar: a comma puts more emphasis on the adverbial constituent so separated from the sentence. My advice would be thus: add a comma if you feel it is necessary; when it doubt, leave it out.
