Is it possible to ignore the definition entered for a word in favor of my own definition? A great example of this need would be for "seltsam," which until yesterday was defined with adjectives like "strange" and "odd." Now it's defined as "rare," which doesn't appear in any of the dictionary definitions I can find for "seltsam." (It is, however, the definition for "selten.")
Similarly, the definition for a word like "gewaltig" is more than merely "enormous" and "lassen" doesn't simply mean "to leave." I would love to be able to see multiple definitions of words, because it would give me a much clearer sense of how the word is used and what it means.
Memrise has been a really powerful tool in growing my German vocabulary (thank you!) but I also fear that its limited definitions could lead to either bad habits or misuse of words.
