I am going through the Drill Sets and occasionally find myself feeling like I was left with little insight into the nuances between some choices. For instance, page 57, #7, I knew the second blank, but was unsure on Maven or Virtuoso in the first. Dictionary definitions I came across elucidated very little.
For example: American Heritage Dictionary for English Language defines maven as
"A person who has special knowledge or experience; an expert."
Random House Kenerman Webster's College Dictionary has nearly the same definition for virtuoso:
"a person who has special knowledge or skill in a field."
American Heritage defines virtuoso as:
"1. ‌ A musician with masterly ability, technique, or personal style.
‌2. ‌ A person with masterly skill or technique in the arts.
‌3. ‌ A person with a strong interest in the fine arts, especially in antiquities."
Rereading the question in the drill set, it says "A perfectionist in all things, Joseph expected to immediately become _____ and was downtrodden indeed when he remained a _____ despite his best efforts.
"Despite his best efforts" the word would be something you strive for through practice or accumulation, whereas having a masterly skill or technique seems more innate.
I finally went to Wikipedia and found a possible difference.
A maven is supposedly an expert in a field and seeks to teach others, whereas a virtuoso shows outstanding ability in a particular field, especially arts. Maven also derives from Hebrew for a man who understands based on the accumulation of knowledge.
So, are these the most salient differences? Is there a nuance I'm missing?
Any help would be appreciated. Thanks!
