is "six inches of snow are predicted, I'd better find my boots" a run on, simple or compound sentence. I am pretty sure its not a compound because there is no coordinate conjunction but i am not sure if it is a simple or run on sentence

After re-reading your post above, What do YOU think?

This is a run on sentence.

To determine whether the sentence "Six inches of snow are predicted, I'd better find my boots" is simple or a run-on, let's first understand the definitions of these sentence types:

1. Simple Sentence: A simple sentence consists of a subject, a verb, and expresses a complete thought.

2. Run-on Sentence: A run-on sentence occurs when two or more independent clauses are incorrectly joined together without proper punctuation or coordinating conjunctions.

Now, let's analyze the given sentence:

"Six inches of snow are predicted, I'd better find my boots."

This sentence contains two independent clauses: "Six inches of snow are predicted" and "I'd better find my boots." These clauses could function as separate sentences on their own. However, since there is no coordinating conjunction or punctuation separating the clauses, it suggests that the sentence is a run-on.

To correct the run-on, you can either use a coordinating conjunction ('and', 'but', 'or', etc.) to connect the two independent clauses, or you can separate them into two separate sentences:

Option 1 - Using a coordinating conjunction:
"Six inches of snow are predicted, and I'd better find my boots."

Option 2 - Separating into two sentences:
"Six inches of snow are predicted. I'd better find my boots."

In either case, you will have avoided the run-on sentence and created a clearer, more grammatically correct sentence.
