hello grammarians today Paige and I are going to teach you all about your new best friend of the comma it is a piece of punctuation that has many many many functions and we're just going to broadly overview them today the comma is an extremely powerful piece of punctuation can do a whole bunch of stuff so Paige what is like the most pertinent or important thing that the comma does I would probably say that it is separating sentence elements okay so that's like its broad superpower exactly but it can also but lots of stuff falls under that okay so it's like it has laser vision but it can not only use that laser vision to like boil water but it can also cut through steel exactly so this is like a super superhero punctuation mark it's okay so how is the comma going to save the day today how's it going to make our sentences make sense what are some of the things that it separates so we can separate elements of lists what's so like for lunch I had tofu comma spam comma and seaweed sorry Hawaiian lunch so that's that's something that's a way in which we can so it's separating these elements of this list I guess commas can also separate dates that's right dates and times so for example here in the United States national blueberry muffin day is July 11th and if we wanted to refer to a historical blueberry muffin day let's say July 11th comma 1981 Wow it was the best muffin day ever that I wish I could have been around yeah okay so so a comma can separate lists Nick be used for dates and we can also like set off things at the beginning of sentences like basically everything is great right so the comment has like a bunch of different functions it's like this super useful multi-tool it's the superhero of a piece of punctuation so we're not going to cover all of that in this video the most important thing to remember about the comma is what it does is separate sentence elements it can it can separate clauses it can separate items in a list it can separate dates usually when you're trying to make a separation within a sentence you use a comma so Pete what are some things that commas can't do that's a great question so commas can't go at the end of a sentence okay so I couldn't be like I want to go swimming comma and that would that couldn't like I couldn't end a sentence that way you need to say something after it so this is this is no good or you have to keep going like I want to go swimming and then sailing and then it with a period like that yes okay so that would be fun that's totally fine usage for a comma if it's in the middle of a sentence but not at the end of a sentence right okay so commas only go in the middle yeah so comma separates stuff which therefore means it has to be on it has to be in between something right there has to be something to the left and something to the right cool all right that's that's a comma yeah would you say I think we have successfully met the comma cool you can learn anything Dave it out page out
