If it is the last word in the sentence than yes you would use the comma. Commas are so you could take a little rest between words.
Examples:
I like cotton candy, too!
Your at this park, too?
I can't believe you did this to me, too!
You gossip, too?
No, you do not need a comma before the word "too" if it is the last word in the sentence.
No, typically a comma is not used before the word 'please' when it is the last word in a sentence. You can simply end the sentence with 'please' without a comma.
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.
Yes, a comma is usually placed before the word "or" when joining two independent clauses in a sentence. This is known as the serial comma or Oxford comma.
A comma is typically placed before "or" when it separates independent clauses in a sentence. However, a comma is not needed after "or" in most cases.
Before
In general, when "but" is used as a conjunction, a comma is not needed before it. However, if the phrase following "but" is an independent clause, then a comma is typically placed before "but."
Say your sentence aloud. If you find you pause before the word 'therefore', you will probably want to insert a comma. If you do not pause, no comma is required. Use a comma when the sense requires it, not because you have a specific word in your sentence.
Not necessarily. Commas are a feature of sentence structure. There is no word or phrase in English that requires a comma.
No, typically a comma is not used before the word 'please' when it is the last word in a sentence. You can simply end the sentence with 'please' without a comma.
A comma is not typically used before "therefore." However, a comma may be used after "therefore" to separate it from the rest of the sentence when it is starting the clause.
The comma goes before the word "but." For example: I was going to spell the word "comma" right, but then I fell into a coma.
Depending on what the sentence is about you may use a comma before 'called';however, in some instances you may not be allowed to place a comma before the word called.
No you don't.
It depends on the sentence.
A comma typically comes before the word "so" when it is used as a conjunction to connect two independent clauses. For example: "I was feeling tired, so I decided to take a nap."
Nope.
