Democracy is a noble goal; it is important, however, to protect the minority from the tyranny of the majority.

1. Simple Sentence
2. Compound Sentence
3. Complex Sentence
4. Compound-Complex Sentence

Which do you think it is? Why?

I'm think it's a complex sentence because it has an independent clause a dependent clause and the subordinator- however but i'm not sure

Does compound- complex mean it has a independent clause, dependent clause, subordinator and conjuction?

Compound = 2 independent clauses, joined correctly

Complex = 2 independent clause + at least 1 dependent clause

Compound-complex = 2 independent clauses, joined correctly + at least 1 dependent clause

I see only two clauses here, joined by the semicolon. I don't see any dependent clauses.

"However" is not a subordinating conjunction. Here is a good list:

There is no dependent clause because both clauses could stand as independent sentences:

Democracy is a noble goal.
and
It is important, however, to protect the minority from the tyranny of the majority.

What type of sentence is the original?

Ohhhh the semicolon takes the place of the conjuction. So it would be a compound sentence?

Exactly!!

Congrats!

Thanks can you help with somemore lol?

Sure. I'll be gone for the rest of the morning (I'm in Central time), but please post your questions. If I'm not here to answer, there are at least three other teachers who are well versed in English grammar who can help.

The given sentence is a simple sentence.

A simple sentence consists of a single independent clause that expresses a complete thought. In this case, the sentence states a clear idea: "Democracy is a noble goal."
