vocabulary profiling

I thnik  between non-native and native speakers both parties can be successful in a vocabulary test because there can be a non native student that has a vast knowledge of vocabulary as well as there can be a native student that is absolutely terrible in acquiring their own vocabulary. We can never predict as there are extraordinary cases between the capacity and knowledge of words in English

I was not too surprised when I see the frequency of an unpredictable word because language is like a deep sea that we can explore, we can find that what we previously thought about a word to be actually other way around. That is how mystical the languages are. The frequency of words definitely vary between American English and British English
