Parsing: Analysis of sentences.
A subject and a single verb in the proper role of a verb: A clause.
[Not counting 3rd/5th forms and "to + verb" structures]
A sentence having a single clause: A simple sentence.
A sentence having two or more equally prominent clauses: A compound sentence.
[Recall Connections studied earlier.]
A sentence having one main clause and one or more other clauses operating as the subject/object (noun), qualifying (restricting) a noun/pronoun (adjective) or something else (adverb): A complex sentence.
A sentence may also be of a more involved structure. At the top level, it may show one structure but individual clauses may show different kinds of interior structures.
Some examples from "The Resident Patient" by Sir Arthur Conan Doyle.
