Commas with an appositive is basically a series of words put after another word to explain your sentence better or make it more clear. The words you add are called appositives; they’re separated with commas. If you take out the appositive, you should still have a full sentence.
Examples On Monday, the 17th of May, I bought my dog. The bag, filled with groceries, broke. The flower, on my windowsill, blossomed this morning.
When the noun you’re using is a short name you typically don’t use commas. For example: This is my friend Josh.
When you use commas with nouns of direct address you put the names of the people you’re talking to in the sentence. You separate the names with commas.
Examples • Watch out, Josh, your going to fall! • Quickly, kids, before the time runs out! • You know, Coach, I haven't double shifted yet.
Activities Insert the commas where they are needed. • The paper from my printer was all gone. • The light in my bedroom burnt out. • You know Dad you haven't payed me back yet. • The leaves on the tree were changing colors. • So Dan how was school today? • The dogs at the park barked very loudly.
