compoundcomplex

Compoundcomplex is a term used to describe a sentence construction that blends features of both compound and complex sentences. In standard grammar, a compound-complex sentence contains at least two independent clauses and at least one dependent (subordinate) clause. The term is commonly written as compound-complex sentence; some materials may present the form without a hyphen or with a space, such as compoundcomplex.

Its structure includes multiple independent clauses—capable of standing alone—linked by coordinating conjunctions (and, but, or, etc.) or by punctuation, together with at least one dependent clause introduced by a subordinating conjunction (because, since, although, while, when, if, after, before, etc.) or a relative pronoun (who, which, that). The dependent clause can precede, follow, or appear in the middle of the sentence.

Examples: Although she was tired, Maria finished her report, and she submitted it before the deadline. The committee approved the proposal because it met the criteria, and several members suggested minor revisions.

Differences and usage: A compound sentence has two independent clauses; a complex sentence has one independent clause plus at least one dependent clause; a compound-complex sentence has both. This structure allows nuanced relationships, such as cause and effect, contrast, or chronology, within a single sentence. However, overuse can hinder readability, so writers should balance complexity with clarity.
