I want to practice some words/verbs like these:
"absetzen/aufsetzen, bemerken/merken, abheben/aufheben"
So I mean words that are similarly written but the beginning is different as illustrated. How do you name these kinds of words? Once I know, I'll check Google for a list of words or other learning materials related to those.
Apart from the name, I am happy to hear if you have tips/references to recommend for learning them or general comments.
