Several years ago I took the Graduate Record Exam (GRE) so I could get into grad school. In addition to the quantitative (math) and analytical writing sections the exam includes a section devoted to analogies, completions, and reading comprehensions. This “verbal” section is all about the vocabulary.
Look, I know words. I use words all the time. But the vocabulary tested on the GRE are unlike any words I (or any normal person) use in day-to-day life. They are long, difficult-to-pronounce words with multiple syllables and limited conversational value. Unfortunately, they are also required knowledge if you want to be considered educated enough to be educated.
