How do you join two independent clauses and write a grammatically correct compound sentence Hannah jammed her thumb Kayle almost broke hip elbow?

Here's how to fix the sentence:

Option 1: Using a coordinating conjunction

* Hannah jammed her thumb, and Kayle almost broke her hip and elbow.

Option 2: Using a semicolon

* Hannah jammed her thumb; Kayle almost broke her hip and elbow.

Option 3: Using a conjunctive adverb

* Hannah jammed her thumb. Moreover, Kayle almost broke her hip and elbow.

Explanation

* Independent clauses are complete sentences with a subject and verb.

* Coordinating conjunctions (for, and, nor, but, or, yet, so) connect two independent clauses. They require a comma before the conjunction.

* Conjunctive adverbs (however, therefore, meanwhile, etc.) connect two independent clauses with a semicolon before the adverb and a comma after it.

Important Note: It's important to clarify that "Kayle almost broke her hip *and* elbow." This is more accurate than "her hip elbow" which doesn't make grammatical sense.
