Should I use a comma after a time phrase such as "in the meantime"?
A time phrase is something that gives details of the time that something happened. It might be a single word or a complete phrase. Some examples of time phrases are tomorrow, at 2pm, five hundred years ago, and in the meantime.
When a time phrase adds information to an independent clause or sentence that follows it then it should be followed by a comma. If the phrase or sentence comes before the time phrase then it shouldn't have a comma before it.
Here's an example:
- Correct: Five hundred years ago, there were no grammar books.
- Incorrect: Five hundred years ago there were no grammar books.
- Correct: There were no grammar books five hundred years ago.
- Incorrect: There were no grammar books, five hundred years ago.
Here's another example:
- Correct: Yesterday, there was no new news.
- Incorrect: Yesterday there was no new news.
- Correct: There was no new news yesterday.
- Incorrect: There was no new news, yesterday.
