Linking words that work (and the ones that lose marks)

Mechanical Firstly / Secondly / Thirdly is one of the fastest ways to a Band 6. Working sets per relationship — adding, contrasting, cause/effect, conclusion — plus the two linker mistakes that flag you immediately.

Linking words (cohesive devices) are how examiners measure your Coherence & Cohesion score. Most students over-usethe obvious ones (Firstly, Secondly, In conclusion) and don’t reach for the natural ones. The trick is to vary themand use ones that fit the actual relationship between your sentences. This guide gives you a working set per relationship type plus the linkers that actually cost you marks.

Working sets by relationship

Adding

Furthermore / Moreover
Adding a stronger or related point. Slightly formal — perfect for Task 2.
In addition
Neutral ‘and also’. Safe everywhere.
What is more
More conversational; works in introductions.

Contrasting

However
The default — but don’t open every body paragraph with it.
On the other hand
Use it ONCE per essay, when comparing two sides directly.
Nevertheless / Nonetheless
‘Despite that’ — slightly higher register than however.
While / Whereas
Mid-sentence connectors. Read more naturally than starting with However.

Cause & effect

As a result / Consequently
Strong consequence statement.
Therefore / Thus / Hence
Logical conclusion. Use sparingly — too formal for every paragraph.
This leads to / which leads to
Mid-sentence cause-and-effect, more natural.
owing to / due to
Followed by a noun phrase, not a clause: 'owing to higher prices' (✓), 'owing to prices rose' (✗).

Examples & emphasis

For instance / For example
Same meaning. Vary between them so you don't repeat.
In particular / Notably
Singling out the strongest example — sounds advanced.
Indeed / In fact
Reinforcing the previous point. Use with caution; one per essay.

Conclusion

In conclusion / To conclude
Standard. Pick one and don't use both.
Overall
Slightly more natural — works in Task 1 too.
On balance
When you've weighed two sides — fits discuss-both-views questions.

Over-mechanical

Firstly, online learning is convenient. Secondly, it is cheap. Thirdly, it is flexible. In conclusion, it has many advantages.

Cohesive but natural

Online learning offers two main advantages. The first is flexibility — students can attend lectures around their work schedules. The second, and arguably more important, is cost: a year of online study at most institutions costs a fraction of on-campus tuition.

Pick the right linker

  1. 1

    Many cities have invested heavily in cycling infrastructure. _______, congestion has only worsened in most of them.
    The relationship is contrast — the second clause defies the expectation set up by the first.

    Pick one. You'll see why straight away.

  2. 2

    The vaccine had been distributed unevenly across the country. _______, infection rates remained high in rural areas long after they fell in cities.

    Pick one. You'll see why straight away.
