Before identifying what type each sentence is, one must understand what a clause is. A clause is a group of words having a subject and a verb, it can be dependent (when it does not express a complete thought on its own) or independent (when it expresses a complete thought on its own).
Now, a simple sentence is one consisting of only one independent clause, a compound sentence is a sentence containing two or more independent clauses (that may be joined by a semicolon or coordinating conjunction), a complex sentence is a type of sentence made up of one independent clause, and one dependent clause (often introduced by a coordinating conjunction), and a compound-complex sentence is one comprised of at least two independent clauses and one or more dependent clauses.
1. They finished the work: S
This sentence consists of only one independent clause (the clause âThey finished the workâ expresses a complete idea on its own). Subject: They, Verb: finished.
2. They finished the work before we did: CX
It is complex because it has an independent clause âThey finished the workâ, and the dependent clause âwe didâ introduced by the coordinating conjunction âbefore.â
3. They went home, but we had to work for two more hours: C
This sentence is compound because it has two independent clauses: âThey went home,â and âwe had to work for two more hoursâ joined by the conjunction âbut.â
4. Because they had finished their work, they went home, but we had to stay longer: CCX
It is Compound-Complex: it contains two independent clauses: âThey went home,â and âwe had to work for two more hoursâ joined by the conjunction âbutâ and one dependent clause (âthey had finished their workâ) introduced by âbecause.â
