Combine Your Ideas in Correct Sentences You should now have some idea of how to organise your ideas at the paragraph level using different organisational patterns, transition words and repeated nouns and pronouns to connect your ideas to show support for the topic sentence. Of course, you need to combine your ideas at the sentence level too. One way you can do this is by using coordinating
and subordinating conjunctions. Join sentences using coordinating conjunctions The lecturer sat down.The student remained standing. These two sentences can be joined by using the coordinating conjunction but and written as: The lecturer sat down but the student
remained standing. Notice that but not only joins the two sentences but also indicates the relationship between them. The most common coordinating conjunctions are and, but and or. Some examples of their usage are shown below. Join sentences using subordinating conjunctions Juliana went shopping – a main clause Juliana went shopping as soon as
she got her monthly salary.
Compound sentences contain two or more independent clauses joined by coordinating conjunctions. Both clauses have equal importance. Example:Coordinating conjunctions

You can do primary research or go to the library and find some data.
In addition to coordination, you can also use subordinating conjunctions to connect sentences. The only difference is that subordinating conjunctions link a main clause and a dependent or subordinate clause. Example:
she got her monthly salary – subordinate clause
You can see in the above example that the main clause makes complete sense on its own but the subordinate clause does not. Thus, it needs the main clause to make meaning, which is why it is called the subordinate clause.
Below is a list of some subordinating conjunctions, their functions and examples of their usage.
Subordinating conjunctions | Function | Examples |
while, whenever, after, etc | time | The lobby group opposed all proposed measures after its leader was reprimanded by the lower court for illegal protest. |
where, anywhere | place | There is heavy breeding of mosquitoes where the patients live. |
because, since, as | reason | Those in the category of non-obese claim to walk briskly every evening because they know the importance of exercise. |
Conclusion
Remember that every essay must have a thesis statement, which controls all the ideas in it. Likewise, every paragraph is controlled by a topic sentence, which is supported by ideas arranged in a logical organisational pattern. The connections between these ideas are made clear by transitions and the repetition of nouns and pronouns and, within sentences, by coordinating and subordinating conjunctions. The key thing to remember is that,
in developing your academic essay, you must present your ideas in a logical and organised way.

We saw in sentence structure that a compound sentence is two [or more] independent clauses joined by a coordinating conjunction or semicolon. So a compound sentence is like two or more simple sentences added together. A compound sentence does not contain any dependent clauses.
- I like coffee. Mary likes tea. → I like coffee, and Mary likes tea.
- Mary went to work. John went to the party. I went home. → Mary went to work, but John went to the party, and I went home.
- Our car broke down. We came last. → Our car broke down; we came last.
Joining Compound Sentences with Coordinating Conjunctions
Usually, we join independent clauses with one of the seven coordinating conjunctions.
The term coordinating conjunction sounds complicated, but in fact there are only seven of them and they are all short, one-syllable words: For—And—Nor—But—Or—Yet—So — remember them with the mnemonic FANBOYS.
The most common of these coordinating conjunctions are and, but and or, in that order. Note that a comma [,] must come before the coordinating conjunction except when the clauses are short [in which case the comma is optional].
and
The and conjunction is the most common conjunction. It has several uses.
- We use and to join two clauses that have equal value, for example: London is in England, and Rome is in Italy.
- We use and to join two clauses when the second clause happens after the first clause, for example: There was a big bang and the lights went out.
- We use and to join two clauses when the second clause is a result of the first clause, for example: He went to bed early, and the next day he felt better.
but
We use the but conjunction to introduce a clause that contrasts with the preceding clause, for example: Mary ran fast, but she couldn't catch John.
or
We use the or conjunction to join two alternative clauses, for example: Will Mary go, or will John go?
nor
We use the nor conjunction to join two alternative clauses when the first clause uses a negative such as neither or never. In this case both clauses are untrue or do not happen, for example: Mary never wrote the letter, nor did she call him. [Note the inversion of subject and auxiliary: did she.]
for
We use the for conjunction [meaning something like because] to join two clauses when the second clause is the reason for the first clause, for example: He felt cold, for it was snowing.
yet
The yet conjunction is similar to but. It means something like but at the same time; but nevertheless; but in spite of this. As with but, there is a contrast between the clauses, for example: I have known him for a long time, yet I have never understood him.
so
The so conjunction means something like therefore; and for this reason. We use so to join two clauses when the first clause is the reason for the second clause, for example: He was feeling sick, so he went to the doctor.
Note that when using a coordinating conjunction, you can [if you wish] remove any subject word and modal auxiliary from the second clause. [This is not possible with subordinating conjunctions.]
Joining Compound Sentences with Semicolons
Occasionally, we join independent clauses with a semicolon [;].
- He studied very little; he failed his exams.
- The sky is cloudy; it's going to rain.
- Ram cut the grass; Ati trimmed the hedge; Tara watched.
Joining Compound Sentences with Conjunctive Adverbs
We can also join independent clause with words and phrases like moreover, however, at least [conjunctive adverbs]. In this case, the conjunctive adverb must be preceded by a semicolon [;] and followed by a comma [,].
Look at these examples:
- John loves Mary; however, Mary doesn't love John.
- Salad is not expensive; moreover, it's very healthy.
- What he did was incredible; in fact, I can hardly believe it.
comma + coordinating conjunction | Independent clause | , for , and , nor , but , or , yet , so | independent clause. |
semicolon | ; | ||
semicolon + conjunctive adverb + comma | ; moreover, ; however, ; indeed, ; therefore, ; at least, |
The table shows all seven coordinating conjunctions, and a few conjunctive adverbs as examples.
Do not try to join independent clauses with a comma alone—that's impossible!
