Word salad is a type of writing that is made up of a bunch of random words put together in a way that does not make much sense. It might look like this:
"The door heavy blue window red moon apples oranges"
In this example, the words are all linked together but they don't mean anything together. It's like a puzzle with all the pieces in the wrong places. When you try to make sense of word salads, it's like trying to put together a jigsaw puzzle without ever seeing what it's supposed to look like in the end.
