Not necessarily. There is no word or phrase in English that requires a comma before or after it. Commas are features of sentence structure, not of words or phrases.
Often, but not always: it depends on how you are using the word.
When "but" introduces an independent clause, you need to use a comma before it:
I had planned to buy a pumpkin, but there were none left.
There are, however, other ways that "but" can be used that do not require a comma before:
It is usually appropriate to place a comma before "but." One should not use a comma after "but."
A comma before "and" depends on the context. Use a comma before "and" in a list of items (e.g., red, blue, and green). However, do not use a comma before "and" when it connects two independent clauses unless it is needed for clarity or to avoid confusion.
a comma should always precede but. Especially if it is joining a compound sentence. For example,Michael is tall, but Shawn is taller.I want to go to school, but I have to do my homework.
No, a comma is not typically used before the word "apparently" at the end of a sentence.
Maybe. Maybe not. Sometimes. Othertimes not. Whether the use of a comma is or is not appropriate depends on the context.
no
It is usually appropriate to place a comma before "but." One should not use a comma after "but."
In a company name such as "ABC Corp," do not use a comma. However, use a comma in the formulation, "ABC, Inc."
No of course not!only when you have run on sentences.
A comma before "and" depends on the context. Use a comma before "and" in a list of items (e.g., red, blue, and green). However, do not use a comma before "and" when it connects two independent clauses unless it is needed for clarity or to avoid confusion.

Not necessarily. It depends on the context. If you think in terms of placing a comma after a word, rather than before one, it might be helpful.
