SENTENCE COMBINING / JOINING / SYNTHESIS
Once you have mastered writing a clear, grammatically correct simple sentence (a sentence that contains a subject and a predicate and expresses a complete thought), you can begin to improve your writing by practicing combining sentences. Combining sentences not only lends variety to your writing but also helps the reader to follow the direction of your argument smoothly. It adds to the tools you have to create dramatic emphasis and thus to more effectively persuade your audience.
Besides the simple sentence, you can create three more sentence patterns by combining sentences through coordination and subordination:
A compound sentence, which consists of two or more main or independent clauses (clauses that can stand alone as sentences) joined by a coordinating conjunction and a comma, by a semicolon alone (when the thoughts expressed in the clauses are of relatively equal value), or by a conjunctive adverb (e.g., therefore, however, instead, then) and a semicolon;
A complex sentence, which contains one independent clause and one or more subordinate clauses;
A compound-complex sentence, which has two or more independent clauses and at least one subordinate clause.
Compound Sentences
Compound sentences created with coordinating conjunctions
The coordinating conjunctions are and (shows addition), or (shows choice), but and yet (show contrast), for and so (show logical consequence), nor (shows addition of a negative point). Together with a comma, coordinating conjunctions can join two independent clauses.
Example:
Life is short. [independent clause]
Art is long. [independent clause]
Life is short, but art is long.
Compound sentences created with a semicolon
This method of joining sentences is only recommended for sentences whose ideas are related and of equal significance.
Example:
The house was empty; everyone had gone.
Compound sentences created with a conjunctive adverb and a semicolon and a comma (when the conjunctive adverb immediately follows the semicolon)
Examples:
The price of oil has risen sharply; therefore, wood stoves are popular again.
or
The price of oil has risen sharply; wood stoves are therefore popular again.
A conjunctive adverb is a word or phrase that indicates the relationship between clauses it joins but is usually weightier and more emphatic than a conjunction. Conjunctive adverbs specify one of the following relations:
1. Addition: besides, furthermore, moreover, or in addition
The general had complete confidence in his soldiers' training and valor; furthermore, he considered his battle plan a work of genius.
2. Likeness: likewise, similarly, or in the same way
Many young Englishmen condemned the English war against France in the 1790s; likewise, many young Americans condemned the American war against Vietnam in the 1960s.
3. Contrast: however, nevertheless, still, nonetheless, conversely, otherwise, instead, in contrast, or on the other hand
Einstein's theory of relativity was largely a product of speculation; experiments made within the last fifty years, however, have confirmed its basic points.
4. Cause-and-effect: accordingly, consequently, hence, therefore, as a result, or for this reason
Carl spent too many nights going to parties his first semester in college; for this reason, he missed more classes than he should have.
5. Means-and-end: thus, thereby, by this means, or in this manner
When our guinea pigs became listless, we took them to the doctor; thus, we were able to stop their illness before it became too grave.
6. Reinforcement: for example, for instance, in fact, in particular, or indeed
My son hates tee-ball; in fact, he hates it so much that he walked from third base during his last game of the season and stomped on home plate.
7. Time: meanwhile, then, subsequently, afterward, earlier, and later
We went to the voodoo museum; afterward, we went to a cemetery and found the grave of Marie Laveau.
Complex Sentences
A sentence is complex if it contains one main clause and one or more subordinate clauses. Some common subordinating conjunctions include after, although, as, as if, because, before, even though, if, in order that, once, since, so that, than, that, though, unless, until, when, where, while.
Example:
The railroad finally came, though many businesses had already left the area by then. [Main clause followed by subordinate clause]
Compound-complex sentences
Compound-complex sentences have two or more independent clauses and at least one subordinate clause.
Examples:
Even though government aid finally came, many people had already been reduced to poverty, and others had been forced to leave the area. [Subordinate clause, then main clause, then another main clause]
Some of the teachers who had left the area moved back to their original schools, but several years passed before salaries were raised enough to entice more teachers to return. [Main clause containing subordinate clause, then another main clause, then another subordinate clause]
