A. What is Cohesion and Why Use Complex Connectors?
Cohesion is the "grammatical glue" that links sentences and ideas, ensuring a text flows smoothly. Basic connectors like and, but, so are the foundation, but at an advanced level, using more complex connectors adds precision, formality, and sophistication to your writing.
These connectors act as powerful signals, showing the logical relationship between different parts of your text.
B. Connectors of Cause and Effect
Go beyond because and so to express causality with more nuance.
| Function | Connector | Grammatical Note | Example |
|---|---|---|---|
| Cause | owing to / due to | Followed by a noun phrase. | Owing to a mechanical failure, the flight was cancelled. |
| on the grounds that | Followed by a clause. Very formal. | He was fired on the grounds that he had violated company policy. | |
| by virtue of | Emphasizes that a quality is the cause. | She got the job by virtue of her extensive experience. | |
| Effect | consequently / as a result | Links two independent sentences. | The company lost money. Consequently, several staff were laid off. |
| hence / thus | Formal. Often used to introduce a logical conclusion. | The evidence was flawed; hence, the verdict was overturned. |
C. Connectors of Condition
Move beyond a simple if to specify the exact conditions required.
| Connector | Meaning / Nuance | Example |
|---|---|---|
| provided that / on condition that | A strong, formal condition; the only condition. | We will sign the contract, provided that you guarantee delivery by May. |
| assuming that | Based on a probable assumption. | Assuming that the traffic is light, we should arrive by 6 PM. |
| so long as / as long as | Emphasizes the duration of the condition. | You can borrow the car so long as you promise to be careful. |
| unless | A negative condition (if... not). | We will not proceed unless we receive the payment in full. |
D. Connectors of Contrast and Concession
These are crucial for building balanced arguments.
| Connector | Grammatical Note | Example |
|---|---|---|
| in spite of / despite | Followed by a noun phrase or -ing form. |
Despite the pouring rain, they continued the match. |
| while / whereas / whilst | Used to show direct contrast between two things. | Whereas the old system was inefficient, the new one is highly streamlined. |
| notwithstanding | Very formal. Means "in spite of." Can come before or after the noun. | Notwithstanding the fierce opposition, the law was passed. / The opposition notwithstanding, the law was passed. |
Note: Never use "despite of." It is a common error. It's either despite + noun or in spite of + noun.
E. Creating Cohesion with Participial Phrases
A highly effective C2-level technique is to use participial phrases (-ing or -ed forms) to link ideas. This condenses two sentences into one, creating a more fluid and sophisticated text.
1. Present Participle (-ing)
Used when the subject is performing two actions at the same time, or one action causes another.
Instead of: She opened the drawer and she took out a file.
Better: Opening the drawer, she took out a file.
2. Past Participle (-ed)
Used to start a sentence with a passive idea.
Instead of: The report was written by experts, and it is very convincing.
Better: Written by experts, the report is very convincing.
3. Perfect Participle (Having + past participle)
Used to show that one action was completed before the next one started.
Instead of: He finished his speech and then he sat down.
Better: Having finished his speech, he sat down.
F. Common Error: The Dangling Modifier
This error occurs when a participial phrase doesn't logically connect to the subject of the main clause.
- ✗ Dangling: Having finished the report, the computer was turned off.
- (This sentence implies the computer finished the report.)
- ✓ Correct: Having finished the report, I turned off the computer.
- (The phrase correctly modifies "I".)
Always ensure the "doer" of the action in the participle is the subject of the next clause.
