I am trying to figure out the meaning of the compound nouns in the German language. I don't know what is expressed by combining words that way. I don't understand it. Here are few examples and questions:
1) die Deutschschülerin vs. die deutsche Schülerin
My current hypothesis:
- die Deutschschülerin - the female pupil learning German, she can have any nationality
- die deutsche Schülerin - the German female pupil
2) der Mathelehrer vs. der Tschechischlehrer vs. der Hauslehrer
My current hypothesis:
- der Mathelehrer - the math tutor
- der Tschechischlehrer - the Czech tutor, i.e. a tutor teaching Czech, no matter what is their nationality
- der Hauslehrer - the house tutor? This is really weird, because "Haus" is not a field of study. So in this example the word "Haus" actually refers to the place of the lesson?
3) die amerikanische Deutschschülerin = the female American pupil learning German?
4) Can the word "der Tschechischlehrer" be used to refer to a Czech teacher of Japanese nationality?
5) Can the word "die Deutschschülerin" be used to refer to a German lady?
