When and where? Let’s check it out.
There are many, many times a writer will repeat adjectives. See, where I just used them? It is correct usage and is used for emphasis. Always put a comma between them. It separates them for more emphasis and also lets the reader know that it wasn’t a typo. You wanted to write it like that.
Many writers will pen sentences like this
“The big, red truck entered the yard.”
“The tight young group hung around the campfire.”
See how the subjects of the sentences had two adjectives in the beginning? The first one has ‘big’ and ‘red’. The second one has ‘tight’ and ‘young’ in it. The first sentence has a comma. The second doesn’t. They are both right. How can that be? There is actually a simple way to know when to use a comma between two adjectives.
Can you put ‘and’ in place of the comma and the sentence still make sense?
“The big and white truck entered the yard.” It makes sense. The ‘and’ works, so a comma is to be used. Now, let’s see if how it works with the next sentence.
“The tight and young group hung around the campfire.” Nope. Doesn’t work. You don’t have to put a comma here. Keep the adjectives together without any punctuation separating them.
Does it make sense now? I never knew this but usually followed the rule. It just made sense. Now, there is reasoning behind it.
Commas are one member of the punctuation family that causes writers no end of trouble, but they aren’t horrific beasts. They can be tamed and understood. It just might take us a while to do it.
