Using contracted forms (“don't”, “let's”) in a formal text
Usage of contractions like “it's” and “that's” in textbooks
Should contractions be avoided in formal emails?
Are contractions like “didn't” forbidden in written English?
Is a text written without abbreviations generally considered more refined, well-mannered and couth? For some reason, I have gotten that impression. E.g.
- "It's warm out, isn't it?" vs "It is warm out, is it not?"
- "I can't say" vs "I cannot say"
Are there situations when abbreviations like these should be avoided? What is the popular consensus about their usage?
