Lesson 42 of 46
Formal vs informal English
Match your language to the reader and the situation.
The rules
- 1.Formal writing (reports, cover letters, first emails) avoids slang and often avoids contractions: "do not" rather than "don't".
- 2.Informal writing (messages to friends and close colleagues) can use contractions, short sentences, and everyday words.
- 3.Choose precise words for formal text: "children" not "kids", "request" not "ask for", "approximately" not "about".
- 4.Match your reader: be more formal with clients, senior people, and strangers.
