Mastering Linkers in IELTS Writing Task 2 for a Higher Band

In the official IELTS Writing Task 2 scoring criteria, Coherence and Cohesion accounts for 25% of your total score. To achieve a high band score in this criterion, a thorough understanding and application of cohesive devices is essential.

However, using linking words goes far beyond simply plugging a handful of complex phrases into the beginning of your sentences. In this article, ECE Language Center breaks down essential linking categories according to standard academic writing styles, analyzes the grammatical nature of cohesive tools, and highlights key considerations to help you break through to a Band 7.0+ score.

The Role of Linking Words in Coherence and Cohesion

In the IELTS examiner’s scoring scale, Coherence (the logical flow of ideas) and Cohesion (the structural links between them) are distinct yet closely intertwined categories. Many candidates falsely believe that simply stuffing an essay with complex transitional phrases at the start of every sentence will automatically boost their score. This is a common misconception, as cohesive devices merely act as a visual aid to reveal the logical structure already present in the writer’s thinking.

To truly grasp how examiners evaluate your work, take a look at the distinctions across the official Band Descriptors:

• Band 5.0 (Disjointed or Inaccurate Cohesion): Candidates tend to repeat a few basic linking words or force transitional phrases at the beginning of sentences, distorting the underlying logical relationships.

• Band 6.0 (Mechanical Cohesion / Over-use): Candidates know how to categorize and use linking words, but the flow of the text relies entirely on words placed at the start of sentences (e.g., Firstly, Secondly, Furthermore, However, Therefore). Examiners refer to this as “Mechanical Cohesion”—sentences feel choppy, disconnected, and resemble a fill-in-the-blank exercise rather than a cohesive essay.

• Band 7.0 (Diverse and Appropriate Cohesion): Candidates have mastered the system of linking words, applying them flexibly and accurately for various argumentative purposes (concession, contrast, cause-and-effect). Even at this band, however, minor repetitions or less-than-optimal transitions may occasionally slip through.

• Band 8.0+ (Natural / Subtle Cohesion): At this elite level, cohesive tools are handled smoothly and flexibly. Information flow and ideas are ordered with such natural logic that readers can easily follow the entire essay without being distracted by clunky sentence-initial transitions. Cohesion shifts from surface-level formatting (starting sentences with linkers) to intrinsic cohesion (embedded semantics and underlying thought structures).

The essence of this criterion follows a simple principle: logic creates coherence, while linking words simply make that coherence visible. If the semantic relationship between your sentences is fundamentally flawed in the first place, forcing in words like “However” or “Therefore” will not rescue your argument—in fact, it will only expose the logical breakdown to the examiner. Therefore, the true function of a linking word is to act as a “road sign” guiding the reader, letting them know whether the next idea builds on, contrasts with, or naturally follows from the previous one.

Distinguishing Conjunctions from Conjunctive Adverbs to Avoid Punctuation Errors

The crux of the matter lies not in a word’s meaning, but in its syntactic function within a sentence.

A. Conjunctions

This group includes subordinating conjunctions (Although, While, Whereas, Because, Since, As) and common coordinating conjunctions (But, Yet).

Function: Used to connect clauses within the same sentence. When a subordinating conjunction begins a sentence, it turns that clause into a dependent one, meaning an independent clause must follow to make the sentence grammatically complete.

Punctuation Rules:

• If the conjunction starts the sentence: Separate the two clauses with a comma in the middle. Never place a comma immediately after the conjunction.
• If the conjunction is in the middle of the sentence: Generally, no comma is needed beforehand (for subordinating conjunctions), or a comma is required beforehand (for coordinating conjunctions like “but” or “yet”).

Correct Examples:

While online education offers great flexibility, it requires a high level of self-discipline.

Digital versions are more convenient for commuting, but physical books still offer a superior tactile experience.

Incorrect Example: Although, online learning is flexible. It lacks face-to-face interaction. (Error: placing a comma right after “Although” and incorrectly splitting sentences).

B. Conjunctive Adverbs

This group includes high-level academic words such as: However, Nevertheless, Therefore, Consequently, Furthermore, Moreover, Additionally, Thus, Hence.

Function: Used to establish a semantic relationship between two separate, independent sentences. By nature, they are adverbs and do not possess the syntactic power to directly link two clauses grammatically the way conjunctions do.

Punctuation Rules: This group has flexible yet extremely strict punctuation rules:

• Method 1 (At the beginning of the second sentence): Place it after the period of the first sentence and separate it from the following clause with a comma.
• Method 2 (Connected with a semicolon): Used to link two closely related clauses in a single compound sentence by placing it after a semicolon (;) and before a comma (,).
• Method 3 (Mid-sentence or end of sentence): Insert the adverb into the middle or end of the second sentence, enclosing it with two commas to give the style a smoother rhythm.

Correct Examples:

Method 1: The economic benefits of industrialization are undeniable. However, the environmental costs are often severe.

Method 2: The economic benefits of industrialization are undeniable; however, the environmental costs are often severe.

Method 3: The economic benefits of industrialization are undeniable. The environmental costs, however, are often severe.

Incorrect Example: The economic benefits of industrialization are undeniable, however, the environmental costs are often severe. (Error: using a comma before “however” to join two independent clauses).

Summary Table for Punctuation Checks

To avoid losing precious marks under the Grammatical Range and Accuracy criterion, keep this ironclad rulebook in mind:

Note: Whenever you finish writing a sentence containing a linker, always ask yourself: “Is the word I’m using a conjunction or an adverb?”. If it’s “Although” or “While”, look for the comma in the middle of the sentence. If it’s “However” or “Therefore”, make sure it sits right next to a period or a semicolon. Mastering this punctuation will instantly prove to the examiner that you have a rock-solid grasp of academic grammar.

Categorizing Linking Words by Academic Function

Below is a curated list of conjunctive adverbs and transitional phrases categorized by their argumentative purpose in Task 2 essays:

Category 1: Introducing the First Point

Use these when starting to develop your primary main idea in a body paragraph.

• Firstly (Conjunctive Adverb):

Usage: The most basic and straightforward tool to signal your first point. Suitable for any essay type.

Example: Firstly, job-hopping allows young professionals to quickly diversify their skill sets and gain broader industry experience.

• To begin with / To start with (Adverbial Phrase):

Usage: Natural-sounding, often used to open a series of arguments explaining an issue starting from its root causes.

Example: To begin with, heavy reliance on private vehicles is the primary driver of escalating greenhouse gas emissions in urban areas.

• In the first place (Adverbial Phrase):

Usage: Frequently used in cause-and-effect essays or when emphasizing a core premise or fundamental truth that should have been addressed from the outset.

Example: In the first place, governments should never have permitted the construction of heavy industries so close to residential zones.

Category 2: Adding Information and Developing Ideas

These linking words are used when you want to introduce a new argument in the same logical direction to further substantiate your point.

• Furthermore (Conjunctive Adverb):

Usage: Highly formal. Used when your second point does more than just list another item—it elevates the argument or carries even heavier weight than the previous idea.

Example: Universal healthcare ensures that all citizens have access to essential medical treatments. Furthermore, it alleviates the long-term financial burden on the national economy by promoting preventative care.

• Moreover (Conjunctive Adverb):

Usage: Similar to Furthermore, but often used to broaden the perspective toward a macroeconomic aspect or a natural logical consequence of the previous point.

Example: Excessive screen time triggers sleep deprivation among adolescents. Moreover, it severely limits their opportunities for face-to-face social interaction.

• In addition / Additionally (Conjunctive Adverb):

Usage: Used when adding information or a supporting aspect of equal importance to the preceding point (acting as an equivalent parallel argument).

Example: Implementing carbon taxes encourages corporations to adopt green technologies. Additionally, the revenue generated can be reinvested into renewable energy infrastructure.

Category 3: Contrast and Concession

These are foundational words for demonstrating a candidate’s multi-dimensional critical thinking.

• However / Nevertheless (Conjunctive Adverb):

Usage: Used to pivot an argument or introduce information opposing the preceding sentence. “Nevertheless” carries a stronger formal tone and emphasizes stronger concession (even though the previous point is true, the subsequent event still happens).

Example: Strict penalties can temporarily deter criminal activities. However, they fail to address the root socioeconomic causes of delinquency.

• On the other hand (Adverbial Phrase):

Usage: Typically used when comparing two opposing viewpoints in a Discussion essay. In academic writing, pairing an earlier “On the one hand” with “On the other hand” in a later paragraph creates a remarkably balanced argumentative structure.

Example: On the other hand, opponents of space exploration argue that national budgets should be prioritized for terrestrial issues like poverty.

• In contrast / Conversely (Conjunctive Adverb):

Usage: Used to contrast two trends, demographic groups, or datasets that exhibit completely opposite characteristics.

Example: High-income households often have immediate access to clean energy alternatives. Conversely, low-income families are frequently forced to rely on cheaper, polluting fossil fuels.

Category 4: Cause and Effect

These connectors are used to develop a logical chain of reasoning leading from a phenomenon to its real-world consequences.

• Therefore / Consequently (Conjunctive Adverb):

Usage: Used at the beginning of the second sentence to indicate a logical outcome derived from the cause stated in the first sentence. “Consequently” emphasizes that the result is an inevitable outcome.

Example: Raising chemical fertilizers degrades soil quality over time. Consequently, agricultural yields may face a sharp decline in the long run.

• As a result / As a consequence (Adverbial Phrase):

Usage: Shares a similar function to Therefore, linking cause and effect across two sentences.

Example: Many economic migrants have fled to developed nations. As a result, major metropolitan areas are experiencing unprecedented population pressure.

• Thus / Hence (Conjunctive Adverb / Adverb):

Usage: Alongside sentence-initial use, “thus” and “hence” are frequently used to indicate a consequence right within a complex sentence without needing to split a new sentence, often pairing with a V-ing participial phrase.

Example: The universities have expanded their online programs, thus allowing a larger number of remote students to pursue higher education.

Category 5: Exemplification and Clarification

These connectors are used to ground abstract arguments with concrete details to persuade the examiner.

• For instance / For example (Adverbial Phrase):

Usage: Used to open a sentence containing evidence, statistics, or a specific case proving the preceding topic sentence. You can place this phrase at the start of a sentence or embed it right after the subject.

Example: Modern household appliances have significantly facilitated the cooking process. For instance, automated pressure cookers reduce meal preparation time by half.

• To illustrate / As an illustration (Transitional Phrase):

Usage: Carries a formal tone, typically used when your example is a real-life story or a complex social phenomenon that requires more than a single sentence to unfold.

Example: To illustrate, Scandinavian countries have implemented comprehensive welfare models, which have successfully minimized the wealth gap.

• In other words / That is to say (Adverbial Phrase):

Usage: Used when you have just presented an abstract academic point and want to rephrase it in a more direct, accessible way to ensure clarity for the reader.

Example: The government decided to implement a progressive tax system. In other words, wealthier individuals will be required to contribute a higher percentage of their income to the state.

Stylistic Traps and Linker Overuse in the IELTS Exam

When grading Writing Task 2, examiners evaluate not only the meanings of connectors but also how frequently they appear and whether they fit an academic context. Many candidates fall into two classic traps that lock their scores at Band 6.0.

A. Register Errors

Many learners have a habit of dragging everyday conversational linkers or spoken-style transitions straight into formal essays. This directly hurts their Lexical Resource score.

• Restricted Sentence-Initial Connectors (But, Yet, So):

Nature: These conjunctions are very common at the start of sentences in speech, everyday conversation, or journalism. However, in Academic Writing, isolating them at the beginning of a sentence right before a comma is discouraged because it breaks sentence flow and sounds a bit too casual.

Adjustment: Instead of writing “So, the government should…”, use more formal conjunctive adverbs like Therefore, Consequently, or As a result. Instead of “But, technology has…”, use However or Nevertheless.

• Words to Avoid at the Beginning of Sentences (Plus, Also, In a nutshell, In short):

Nature: “Plus” and “Also” belong strictly to spoken English. Meanwhile, “In a nutshell”, “In short”, and “In a word” are idioms or informal summary phrases. IELTS Academic Task 2 demands absolute formality, making these choices utterly out of place.

Adjustment: Completely replace Plus/Also with Furthermore, In addition, or Additionally. Swap informal summary phrases for standard concluding tools like In conclusion or To sum up.

B. The Trap of Mechanical Cohesion

This is the most common pitfall in Band 6.0 essays. Candidates try to force a linking word at the beginning of every single sentence in a paragraph using a rigid formula.

• Telltale Sign: A four-sentence paragraph where every sentence opens with a linker, such as:

Firstly, governments should invest in education. Moreover, this helps reduce poverty. However, national budgets are limited. Therefore, taxes must be increased.*

• Impact on Band Score: This style makes an essay look like a list of isolated simple sentences glued together with artificial adhesives. Examiners call this “Mechanical Cohesion”. Such writing fails to create a natural flow of information, interrupts the reading rhythm, and directly blocks the essay from reaching Band 7.0 (which demands flexible and appropriate cohesion).

• Solution: In a body paragraph (consisting of a topic sentence, explanation, and example), you should limit yourself to using 1 or 2 sentence-initial conjunctive adverbs for crucial shifts, like pivoting an argument or pointing out a core consequence. In the remaining space, rely on intrinsic cohesive methods (hidden cohesion) to let the information flow naturally and coherently.

Implicit Cohesion: Your Key to Breaking Into Band 7.0+

The defining difference of a Band 7.0+ essay is its remarkably natural sentence flow. Rather than constantly relying on linkers at the start of sentences, high-scoring candidates use implicit cohesive methods (tying ideas together through shared meaning and structure).

A. Pronoun Reference

Use pronouns like it, they, this, these or umbrella noun phrases paired with this/these to represent or recall complex ideas and actions introduced in previous sentences. This technique anchors subsequent sentences to preceding ones without needing mechanical linkers.

Illustrative Example:

• Standard Writing (Band 6.0): Governments should invest more in public transport systems. Moreover, public transport systems can effectively reduce urban traffic congestion. (Repetitive and dependent on sentence-initial linkers).
• Advanced Writing (Band 7.0+): Governments should invest more in public transport systems. This financial commitment can effectively reduce urban traffic congestion. (“This financial commitment” both replaces the prior investment action and adds academic weight to the essay).

B. Lexical Cohesion

This method builds a uniform semantic network throughout a paragraph without depending on mechanical transitional words at the front of sentences.

Illustrative Example:

Well-linked sentence chain: Many children now rely heavily on digital devices for entertainment. This growing obsession with screens often leads to sedentary habits. Consequently, young generations face an increased risk of obesity. (Phrases like digital devices — screens and children — young generations naturally weave an extremely tight semantic web).

C. Domain-Specific Transitions

Instead of falling back on empty sequencing or additive words (Moreover, Furthermore), guide your reader by directly introducing the angle or lens you are about to use for analysis. This technique lends your essay a deeply analytical tone.

Typical Phrases:

• From an economic perspective,…
• In terms of education,…
• From a social point of view,…

Example: From an economic perspective, raising the minimum wage may increase production costs for small businesses.

Test-Day Strategies for Linking Words

When entering the exam room under time pressure, applying a smart linking strategy will help you secure your Coherence & Cohesion score while freeing up mental bandwidth to focus on idea generation.

A. Use Simple Connectors Confidently

Many candidates waste precious time racking their brains for flashy linking words out of fear that using “firstly”, “secondly”, or “finally” will look monotonous. This is a misunderstanding of the scoring criteria. Examiners grade based on argumentative logic rather than deducting points for clear
