4 Formal or informal?

Described image
Figure 11 Formal and informal writing

There are many types of writing style but only two that you need to recognise now: formal and informal.

  • Formal: a style of writing in which standard English is used because you are writing to someone you don’t know or to whom you want to give a good impression.

  • Informal: a style of writing where choice of words and grammar tends to be familiar rather than formal. This is used when you know, or want to get to know, the person you are writing to.

Activity 26 Which is formal and which informal?

Timing: Allow about 5 minutes

Which sentence would be found in a formal report and which in an informal discussion?

  1. They did a brilliant job, particularly considering what a mess things were in before.
  2. The work was completed two days ahead of schedule and achieved a Quality Control score of 95%.


Sentence 1 is the sort of sentence you might expect to hear in a corridor. It is written in an informal, ‘spoken’ style.

Sentence 2 is the sort of sentence you might expect to read in a report. It is written in a formal, business-like style.

Activity 27 When to use formal language

Timing: Allow about 10 minutes

Consider the following situations. Five involve spoken language and five involve written language. For each, select the style of language you think it would be best to use: formal, informal or semi-formal, i.e. somewhere between the two.

If you disagreed with some of the answers, reconsider your understanding of formality and informality. Remember that communicating information clearly requires at least a degree of formality.

Some people think formal language is full of long, unfamiliar words and complicated grammar and is generally – and often unnecessarily – hard to understand. This is not the case. Good formal English is English that conveys information in clear, simple language.

Activity 28 Formal and informal sentences

Timing: Allow about 5 minutes

Look at the following sentences and for each, decide whether it is in a formal or informal style.

Hint Remember, formal English gives precise and generally factual information.

In summary, formal and informal styles of writing are very different and serve two different purposes. Formal writing should be used in a professional setting, for example at work, and contains formal language. Informal writing is more likely to be used when writing to friends or relatives and contains informal language.

Once you have decided if your writing will be formal or informal, you need to think about the tone of your writing. Tone refers to the attitude that your language conveys and applies to both speaking and writing.

Imagine you need to find a plumber to work with you on a house extension project. You email two plumbers asking if they are available. Compare the attitudes expressed in the following two responses.

  • ‘Thank you for contacting me. I would be happy to work with you. Please let me know a suitable time to meet and we can discuss timescales and costs. I look forward to speaking with you soon.’
  • ‘Hiya, too bad! Got no time to help at the mo. Too busy! Wish I’d chosen a different job. Try someone else. Soz!’

The first response is respectful and helpful. The tone is quite formal and polite. The second is disrespectful and unhelpful. The tone is informal and not appropriate.

The second response also expresses personal dissatisfaction. It is unprofessional. How the plumber feels about their job is nothing to do with you. Being professional means putting personal feelings to one side when they have no direct bearing on an interaction.

Formal writing generally requires a polite, respectful tone – especially when you are expressing dissatisfaction. People will always pay more favourable attention to a message that is polite and respectful.

In this section you have looked at:

  • the differences between formal and informal writing
  • identifying different contexts in which formal writing is needed.
