Transitional phrases (also called discourse connectors or linking words) are words and multi-word expressions that signal the logical relationship between sentences, paragraphs, or ideas. They tell the reader whether the next idea adds, contrasts, causes a result, gives an example, or concludes, a distinction the Cambridge Grammar reference sets out in detail. Strong use of transitions is a key marker of cohesion in academic, formal, and professional English.
Categories of Transitional Phrases
| Function | Transitions |
|---|---|
| Addition | furthermore, moreover, in addition, besides, what is more |
| Contrast | however, on the other hand, nevertheless, in contrast, that said |
| Cause & result | therefore, consequently, as a result, hence, thus |
| Example | for example, for instance, such as, namely, to illustrate |
| Concession | admittedly, granted that, although this may be true |
| Summary | in conclusion, to sum up, in brief, overall, to summarise |
| Sequence | firstly, subsequently, meanwhile, finally, in the meantime |
| Emphasis | above all, in particular, especially, notably, indeed |
Punctuation with Transitional Phrases
When a transitional phrase starts a new sentence, follow it with a comma: However, the results were inconclusive. When placed in the middle of a sentence, surround it with commas: The results were, however, inconclusive. Transitional adverbs like therefore and consequently can also follow a semicolon: The data was incomplete; therefore, the study was limited.
Common Mistakes to Avoid
- Using firstly, secondly, thirdly with only one point — ensure there is a corresponding list.
- Using moreover to introduce a contrast — it only adds supporting points.
- Starting every sentence with a transition — creates choppy, unnatural writing.
- Confusing however (linking adverb, needs a semicolon or new sentence) with although (conjunction, within one sentence).
Transitions in Academic Writing
Academic writing relies heavily on transitions to guide readers through complex arguments. A good essay moves smoothly from one paragraph to the next, with transitions signalling the relationship between ideas. Overusing simple transitions like also and and signals lower proficiency; using precise, varied connectors signals B2–C1 competence.

Frequently Asked Questions
What are transitional phrases?
Transitional phrases (discourse connectors or linking words) signal the logical relationship between ideas: addition (furthermore), contrast (however), cause/result (therefore), example (for instance), concession (admittedly), and conclusion (in conclusion). They create cohesion and guide the reader through an argument or text.
What is the difference between 'furthermore', 'moreover', and 'in addition'?
All three add a supporting point. 'Furthermore' and 'moreover' are slightly more emphatic than 'in addition' and typically introduce a stronger or more important additional point. 'Moreover' can suggest the added point is more significant than the previous one. 'In addition' is the most neutral. In practice, all three are interchangeable in most academic contexts.
How do I punctuate a sentence that starts with 'however' or 'therefore'?
When 'however' or 'therefore' begins a new sentence, follow it with a comma: However, the study had limitations. Therefore, further research is needed. When it appears mid-sentence, surround it with commas: The study was, however, limited. It can also follow a semicolon: The data was incomplete; therefore, the results are inconclusive. Never use it like a conjunction joining two independent clauses with only a comma (comma splice).
What is the difference between 'however' and 'although'?
'However' is a linking adverb that connects two separate sentences or clauses separated by a full stop or semicolon: The plan was expensive. However, it was effective. 'Although' is a conjunction that joins two clauses within one sentence: Although the plan was expensive, it was effective. 'However' cannot replace 'although' within a single sentence.
What is the difference between 'therefore', 'consequently', and 'as a result'?
All three introduce a result or consequence. 'Therefore' is the most formal and logical, often used in mathematical or rigorous arguments: X is true. Therefore Y. 'Consequently' suggests a slightly more dramatic or unexpected result. 'As a result' is the most common in everyday academic writing and is neutral in tone. All are interchangeable in most essay contexts.
Can I use 'also' as a formal transition?
'Also' is grammatically correct but is considered informal and weak in academic writing. It adds a point but does not signal the relationship between ideas clearly. In formal writing, prefer 'furthermore', 'in addition', or 'moreover' to add points, or 'additionally' if you need a more neutral alternative. Reserve 'also' for informal contexts or when more precise connectors feel forced.
Is it wrong to start a sentence with 'and' or 'but'?
Starting a sentence with 'and' or 'but' is grammatically acceptable and is common in literary and journalistic writing for rhetorical effect. However, in formal academic writing it is generally preferred to use more formal alternatives: 'furthermore' or 'in addition' instead of 'and'; 'however', 'nevertheless', or 'that said' instead of 'but'. Many style guides still advise against it in academic contexts.
How many transitional phrases should I use per paragraph?
A single well-chosen transition at the start of a paragraph is usually enough to signal its relationship to the previous one. Within a paragraph, use transitions only when the relationship between sentences is not already clear from context. Overusing transitions — especially starting every sentence with one — makes writing formulaic and choppy. Quality and accuracy of choice matter more than quantity.
What are the best transitions for IELTS Task 2 essays?
Examiners reward a range of transitions used accurately. Useful ones include: for addition (furthermore, in addition, moreover); for contrast (however, on the other hand, in contrast); for result (therefore, consequently, as a result); for examples (for instance, for example, such as); for concession (admittedly, granted that); for conclusion (in conclusion, overall, to summarise). Avoid over-relying on 'also' and 'and'.
What is the difference between 'for example' and 'namely'?
'For example' (or 'for instance') introduces one or more illustrative examples from a larger set: Many European countries have introduced carbon taxes, for example Sweden and Germany. 'Namely' introduces a complete, exhaustive list of items just mentioned: Two countries have implemented the policy, namely Sweden and Denmark. Use 'namely' only when listing all members of a set; use 'for example' when giving a partial illustration.
