1. 41 Commas: Series, direct address, multiple adjectives
Series commas are used with three or more items listed in a sentence. The items can be words or phrases and are seperated by commas.
EX. Salamanders, newts, and frogs are amphibians.
Commas are used to separate the name of a person spoken to from the rest of the sentence. This is called a direct address.
EX. When should I have my essay completed, Ms. Holcomb?
When multiple adjectives describe a noun, they are seperated by commas if they are coordinate adjectives.
EX. The dog’s wet, matted fur was difficult to comb.
If you can switch the order of the adjectives without changing the meaning, they need a comma. If you change the meaning by switching the adjectives or create non-sense, no comma is needed.
