Today, we’re going to transform your writing / speaking from simple to spectacular. To excel in your essays, presentations, or any form of communication, you must learn to craft complex, engaging sentences. Basic sentences won’t earn you top marks, so let’s dive into the tools and techniques to make your writing / speaking shine!
1. Mastering Connective Words
Connectors are like bridges that link your ideas smoothly and logically. Pay close attention, students, as these words will elevate the flow of your writing. Here’s a categorized list to guide you:
Adding Ideas: Furthermore, Moreover, In addition, Additionally, Beyond this
Sequencing Points: Firstly, Next, Finally
Comparing Ideas: Similarly, By contrast, In comparison, Whereas
Contrasting Ideas: However, Nevertheless, On the contrary
Showing Cause or Conclusion: Therefore, Consequently, As a result, Due to, Hence
Conditional or Relational Links: Given that, In light of, Provided that, Either…or, Neither…nor
Tip: Use "Although" or "Despite" at the start of a clause to introduce a contrasting idea. Practice these in your next assignment!
2. Building Complex Sentences
Complex sentences combine a main idea with supporting details, making your writing more dynamic. Start your sentences with these subordinating conjunctions or phrases to add depth. Let’s try these together:
Although [situation], [outcome]
When [event], [result]
Before [action], [consequence]
While [ongoing action], [effect]
Until [condition], [result]
If [condition], [outcome]
Since [reason/time], [effect]
Because [cause], [effect]
Due to [reason], [result]
Considering [factor], [conclusion]
Based on [evidence], [statement]
Whether [option], [implication]
Your turn: Pick speaking or writing practice questions below to practice complex sentences
