jon played footbal,yet jonita went shopping. (compound)does the clause yet jonita went shopping is an independent?&why not while jonita went......
Your question is slightly confusing, but hopefully this will help.
Jon played football, yet Jonita went shopping.
This is a compound sentence because both parts have a subject and verb while expressing a complete thought. For example.
Jon (subjet) played (verb) football.
Jonita (subject) went (verb) shopping.
What is perhaps confusing are the conjunctions. Yet is a coordinating conjunction and it joins the two clauses. It is technically not part of either.
While is a subordinating conjunction, and as such it is part of the second clause so here is what they would be like written separately with while.
Jon played football.
While Jonita went shopping.
The subordinating conjunction prevents the second clause from expressing a complete thought by itself as the reader is left wondering what happened “while” Jonita went shopping.
This is sort of similar to your last question with the exception of the word, "yet." This new word, "yet," makes all the difference. Now the sentence is a compound sentence. In other words, what you have is two simple sentences that are joined together by a adversative conjunction. You could have also used the word, "but." It would have produced the same effect. The key point to remember is when you subordinate or make one clause depend on another, then you have a complex sentence. When the sentences can work apart from each other, then you have simple sentences.
