you need a period because etc. is an abbreviation for etcetera.
No.
you do not have to put the comma there
If you mean "do we use a comma before 'etc.'?", then yes we do. Remember to take some paper, a pen, etc. (Oxford ALD).
it needs a comma
Not necessarily. There is no word or phrase in English that requires a comma. More importantly, however, avoid contractions and abbreviations in formal writing. Instead, use " and so forth," or " and the rest."Typically, the abbreviation etc. is used to denote the continuation of a series. As the elements of a series are separated by commas, then yes, a comma is called for in front of etc. For example, in the sentence below:I like all sorts of fruit: blueberries, strawberries, watermelon, etc.
Yes, when saying "thank you" to someone, it is appropriate to use a comma after the words "thank you." For example, "Thank you for your help."
It depends on the context. A comma after "including" is typically used when introducing a list of items. For example: "The ingredients for the cake, including flour, sugar, and eggs, were on the kitchen counter."
A comma is not necessary after "as well as" if it is being used to introduce more items in a list. However, if the phrase "as well as" is used to provide additional information in a sentence, a comma may be needed before and after it to set off that phrase.
Either a period ( . ) or an ellipsis ( . . . ) will go after 'etc' .
"In five years, things happened." Yes you do need a comma.
No. There is no word in English that always requires a comma before it.
Not necessarily. The comma indicates a pause in speech. Use a comma after "but" only to indicate a noticeable pause in speech. If there is no pause, there should be no comma.
