Why Cohesion Matters (কেন গুরুত্বপূর্ণ)

Coherence & Cohesion is its own 25% criterion in Writing (and part of Fluency in Speaking). Band 7 needs a "clear progression" of ideas and a range of cohesive devices used appropriately — not just "Firstly, Secondly, Finally". The best cohesion is often invisible: referencing and paragraphing, not a heavy dose of connectors.

Coherence & Cohesion Writing-এ আলাদা ২৫% মানদণ্ড। Band 7-এ ভাবের "স্পষ্ট অগ্রগতি" ও উপযুক্তভাবে বিভিন্ন cohesive device লাগে — শুধু "Firstly, Secondly" নয়। সেরা cohesion প্রায়ই অদৃশ্য: referencing ও paragraphing।

Over-linking caps you at Band 6. Starting every sentence with "Moreover, Furthermore, In addition" is "mechanical" — the band descriptor that limits your score. Variety and referencing beat quantity.

অতিরিক্ত linker Band 6-এ আটকায়। প্রতিটি বাক্য "Moreover/Furthermore" দিয়ে শুরু করা "যান্ত্রিক" — যা স্কোর সীমিত করে।

Linking Devices by Function (সংযোগ-শব্দ)

Know a range for each function, and vary your choices across the essay. প্রতিটি কাজের জন্য কয়েকটি জানুন এবং রচনায় বৈচিত্র্য আনুন।

Punctuation: a sentence linker at the start takes a comma — "However, …". You cannot join two sentences with only a comma + "however" (comma splice); use a full stop or semicolon: "…rose. However, …" or "…rose; however, …".

বিরামচিহ্ন: শুরুতে linker + কমা। শুধু কমা + however দিয়ে দুই বাক্য জোড়া নয় (comma splice); full stop বা semicolon দিন।

Referencing — The Invisible Glue (রেফারেন্সিং)

Reference words point back to earlier ideas so you avoid repetition. This is what makes writing flow — and it is the cohesion examiners reward most. Reference শব্দ আগের ভাবের দিকে নির্দেশ করে, পুনরাবৃত্তি এড়ায়। এতেই লেখা বয়ে চলে।

The government introduced a new recycling policy last year. This policy has already reduced landfill waste significantly. Such measures, however, require continued public support to succeed. "This policy" and "Such measures" point back — no clumsy repetition of "recycling policy".
Referencing links sentences smoothly and avoids repeating nouns.referencing বাক্য জোড়ে ও noun-এর পুনরাবৃত্তি এড়ায়।
Reference toolPoints toExample
this / thesethe idea just mentionedCars pollute cities. This is a growing concern.
this + noun (very cohesive)summarises the idea…prices rose. This increase hurt low-income families.
such / such a"things of this kind"Such measures are expensive but necessary.
it / theya specific nounThe genome was mapped; it took years.
the former / the latterthe first / second of twoCoal and solar differ: the former pollutes, the latter does not.
the + repeated idea (synonym)avoids exact repetition…a serious problem. The issue affects millions.

Substitution & Ellipsis (প্রতিস্থাপন ও উহ্যকরণ)

Instead of repeating words, replace them (substitution) or leave them out (ellipsis). This keeps writing tight. শব্দ পুনরাবৃত্তির বদলে প্রতিস্থাপন বা বাদ দিন — লেখা ঘন থাকে।

DeviceInstead of…Write…
one / onesa cheap solution or an expensive solutiona cheap solution or an expensive one
do so / do that…to reduce waste, and we must reduce waste…to reduce waste, and we must do so
ellipsis (omit)Some support the plan and some oppose the planSome support the plan and some oppose it / others do not
so / notI think it will happen. / I hope it will not.I think so. / I hope not.

Paragraph Progression (অনুচ্ছেদের অগ্রগতি)

Cohesion is not only about words between sentences — it is about the logical order of ideas. Each Task 2 body paragraph should follow one shape. Cohesion কেবল শব্দ নয় — ভাবের যৌক্তিক ক্রম। প্রতিটি Task 2 প্যারা এক আকৃতি অনুসরণ করুক।

P-E-E-L paragraph: Point (topic sentence) → Explain → Example → Link back to the question. One main idea per paragraph, developed fully.

P-E-E-L প্যারা: Point → Explain → Example → Link। প্রতি প্যারায় একটি মূল ভাব, পূর্ণ বিকাশ।

MODEL BODY PARAGRAPH (well-linked)One key benefit of remote work is flexibility. (Point) Because employees can organise their own hours, they are often more productive. (Explain) A recent shift to home working, for instance, allowed many parents to balance childcare with their jobs. (Example) This flexibility, therefore, benefits both workers and employers. (Link)

লক্ষ্য করুন: "Because", "for instance", "therefore" এবং "This flexibility" — সব একসঙ্গে প্যারাটিকে বেঁধেছে।

Band 6 → Band 7 Errors (সাধারণ ভুল)

✗ MECHANICAL LINKINGFirstly, cars pollute. Secondly, cars cause noise. Thirdly, cars cause accidents. Moreover, cars are expensive.
✓ FIX (vary + reference)Cars create several problems. The most serious is pollution, but they also generate noise and cause accidents. On top of this, running a car is expensive.
✗ COMMA SPLICE with linkerPrices rose sharply, however, wages stayed the same.
✓ FIXPrices rose sharply. However, wages stayed the same. (full stop / semicolon)
✗ VAGUE "it/this"The report criticised the plan and the budget, and it was rejected. (কোনটা?)
✓ FIX…and this plan was rejected. (this + noun = পরিষ্কার)
✗ REPETITION (no referencing)The government built a new hospital. The new hospital is large. The new hospital serves the region.
✓ FIXThe government built a new hospital. This large facility now serves the entire region.

Your Turn — Improve the Cohesion (অনুশীলন)

1 Link with referencing: "Air pollution is rising. Air pollution harms children most."
Show a model answer

2 Fix the comma splice: "Renewable energy is clean, however, it is costly."
Show a model answer
