IELTS Writing Task 2: Master Cohesive Devices (Band 7+)

Cohesive devices are linguistic tools that connect ideas, sentences, and paragraphs to create logical flow in IELTS Academic Writing Task 2. They act as the 'glue' binding your arguments together, demonstrating sophisticated language control required for Band 7+ scores.

Four main categories exist:

1. Reference words create connections by pointing backward or forward: this, these, such, the former/latter. Example: "Technology transforms education. This development raises important questions."

2. Substitution and ellipsis avoid repetition: "Some students prefer online learning, while others choose traditional classrooms" (others = other students).

3. Conjunctions show logical relationships:

• Addition: furthermore, moreover, additionally, likewise
• Contrast: however, nevertheless, conversely, whereas
• Cause/Effect: consequently, therefore, thus, as a result
• Time sequence: subsequently, meanwhile, ultimately

4. Lexical cohesion uses related vocabulary: synonyms (job/employment/occupation), hyponyms (vehicle → car, bus), or repeated key terms with variation.

Cambridge Assessment criterion: 'Coherence and Cohesion' accounts for 25% of your Task 2 score. Examiners specifically assess whether cohesive devices are used "flexibly" and "appropriately" without mechanical overuse.

The golden rule: Quality over quantity. One well-placed cohesive device per 2-3 sentences creates natural flow. Overloading every sentence signals memorized phrases rather than genuine language proficiency, potentially lowering your score to Band 6 or below.

Think of cohesive devices as signposts on a highway—they guide readers through your argument's journey, preventing confusion about direction or destination.

Real-world application in academic discourse:

Consider how The Economist connects complex ideas: "Global inequality continues rising. This trend, however, masks significant regional variations. Consequently, policymakers must adopt nuanced approaches." Three cohesive devices (this trend, however, consequently) create seamless progression through problem → contrast → solution.

Practical example: Environmental essay

Weak cohesion: "Plastic pollution damages oceans. Governments should ban single-use plastics. Companies need to develop alternatives. Consumers must change habits."

Strong cohesion: "Plastic pollution severely damages marine ecosystems. To address this crisis, governments should ban single-use plastics, while simultaneously companies develop sustainable alternatives. Moreover, consumers must fundamentally change purchasing habits, since individual actions collectively create significant impact."

Notice how cohesive devices clarify relationships: this crisis (reference), while simultaneously (contrast + time), moreover (addition), since (cause).

Analogy: Cohesive devices function like joints in the human body. Without them, separate bones (ideas) cannot move together smoothly. Too few joints = rigid, disconnected movement. Too many joints = unstable, overly flexible structure. The skeleton needs precisely placed joints for coordinated motion—exactly like essays need strategically positioned cohesive devices.

Cultural context: Academic English values explicit signposting more than some languages. International students often underuse cohesive devices because their native languages rely on implicit connections. Cambridge examiners expect visible logical bridges between ideas.
