Key concepts in Cohesion & register

Key Idea: This topic turns correct sentences into a good text: link your ideas, keep the right level of formality, and give opinions with reasons.
Connectors by job
JobConnectors
Additionalso, moreover, in addition
Contrasthowever, although, on the other hand
Cause / resultbecause · so, therefore, as a result
Sequencefirst, then, after that, finally
Examplefor example, such as
Conclusionoverall, to sum up, in conclusion

Formal: "Dear…" / "Yours sincerely". No contractions: I am, cannot. request, postpone, assist. "I would be grateful if…".

Informal: "Hi" / "Cheers!". Contractions: I'm, can't. ask for, put off, help. "Can you…?".

Giving & justifying opinions

  1. State it — In my view… / I believe that… / It seems to me that…
  2. Justify it — because… / since… / given that… / for example…
  3. Strengthen it — Admittedly… however… / I see your point, but…
Refer back with it, they, this or such instead of repeating a noun, and never join every idea with "and".

Which connector shows contrast: moreover or however? however. moreover adds an idea.

Who decides the register of your text? The reader and the text type.

What is the classic register mistake? Mixing formal and informal in one text.

Formal word for "put off"? postpone.

What is weak about "I think it's good."? There is no reason. Add because… and an example.

What you'll learn in Topic 3.5
