Noun v verb v the rest

Just FYI, since one of your examples might have more to do with meaning nuance and not with the kanji (pink) vs. vocab (purple) issue:

This may be a problem with meaning nuance. Unfortunately, WK can’t list all the nuance specifics for each item without making the input list ridiculous, so they have a simplified version. You can take a look at this thread for this specific instance. You can also swing by this thread for other nuance questions. You can then add synonyms to those items at your discretion to aid in answering/differentiation.
