Paul, who, without knowing, had already given me a hint, told me the whole truth two days ago.
The word "thereafter" is an adverb. Yes, there is a comma after the word "thereafter" when used in a sentence.
No.
No. After the word and comma can not be used, as it is grammatically inappropriate to use comma after conjunctions such as and, which are called coordinate conjunctions.
In many cases, the word 'however' is followed by a comma. The problem with the word is that one must be careful not to over use a comma. However the word is used,(note that there is no comma used in this connection) the word itself frequently does not need a comma as an automatic punctuation.However, (meaning 'on the other hand') phrasing will most often determine if the word is followed by a comma. These two instances here are examples of when to use or not use the comma as punctuation for this word. When the word is used as a substitute for the phrase 'on the other hand', it is most often followed by a comma.
Yes, a comma is not necessary after the word "yes" when it is used to answer a question. The comma is typically used when there is additional information following the "yes" that needs to be separated.
Yes, typically a comma is used after the word 'furthermore' when it is used to introduce additional information or to connect ideas.
No. There is no word or phrase in English that requires a comma.
No, there should not always be a comma after the word "hopefully." It depends on the sentence structure. When "hopefully" is at the beginning of a sentence, it is often followed by a comma, but if it is used within a sentence, a comma is not necessary.
A comma is typically not used after the word "since" when it is used to indicate time ("since 2010"). However, a comma may be used after "since" when it is being used as a conjunction to introduce a dependent clause ("Since you are here, let's get started").
No, a comma is not typically used before the word "apparently" at the end of a sentence.
No, a comma is not needed before and after the word "again" if it is in the middle of a sentence.
You do not typically use a comma directly before or after the word "but" when it is used as a conjunction to connect two independent clauses. However, you may use a comma before "but" when it is used to introduce a contrasting element in a sentence.
