Complex Sentence – Definition, Structure and Examples

Let us begin by looking at the definition of this type of sentence

What is a complex sentence?

By definition, we will define a complex sentence as a sentence that contains only one main clause or independent clause and, at least, one subordinate clause. The subordinate clause can be as many as possible but at least, one must be present alongside the main clause to make a complex sentence. A subordinating conjunction usually introduces the subordinate or dependent clause.

Complex Sentence Structure

Complex Sentences in English Grammar has its definite structure. In terms of complex sentence structure, its analysis will yield the main clause and at least, a subordinate clause. For instance, He went home after closing from work. There are two clauses here: ‘he went home’ and ‘after closing from work’. The first is an independent clause while the second is a dependent clause. Please note that the subordinate clause is usually introduced by a subordinator or a subordinate conjunction. (See Subordination and Coordination) for more explanations on this.

Bioremediaion

Although the use of genetic engineering to produce microorganisms for waste treatment has received much coverage in the popular press, this approach has been little used to date. Naturally occurring organisms often work better in large-scale treatment systems. Also, companies performing bioremediation have been restricted by rules on the release of genetically engineered microorganisms into the environment. Bioremediation is not always successful; thus, although it is often the most inexpensive method, it is only one of many techniques for dealing with hazardous wastes.

For example, waste mixtures may contain heavy metals, which kill the bacteria capable of metabolizing any organic pollutants in the waste. Bioavailability of the pollutant (the amount actually available to be broken down by microorganisms) may also be a problem: Some organic compounds, such as polychlorinated biphenyls and dioxins, may adsorb onto some soils too tightly to be metabolized. Finally, some organic compounds are very poorly biodegraded. However, when it is effective, biological waste treatment is desirable because it is inexpensive, can be done at the site of pollution, and causes minimal physical disturbance to the surrounding area compared to other methods.

Writing Complex Sentences

There are complex sentence rules. Making complex sentences is not a difficult task. All you need do is generate a clause that is independent. Generate another clause and make it subordinate to the independent clause by introducing a subordinator before the dependent clause. You should note, however, that in writing complex sentences, the dependent clause can come before the independent clause or vice-versa.
