It is important to use an easily comprehensible language. This does not mean a simple version of English, but there are certain fields where caution is required:
- Metaphors and fixed expressions are a good and important spice in one’s oral presentation, but if the use of such expressions becomes too advanced, it hampers the students’ understanding. E.g. I was just making a tongue-in-cheek remark (said it for fun), we’re not out of the woods yet (there is still a long way to go; the problems have not been solved yet), I’m not going to beat around the bush (I will not discuss it without coming to the point), this is only a castle in Spain (a daydream).
Colloquial language and jargon should be avoided. First of all, this goes for swearwords. There is nothing as difficult as swearing in a foreign language, and swearing is much less used in English than in Danish; this applies not least the notorious ‘f-word’ or the word shit.
