The one flaw of E to E dictionary according to me What I am going to say here is just my opinion and I do not intend to insult anyone, any organization.When I was young, E to E dictionary used to be my favourite to look up just because many told E to E dictionary can only improve your understanding of new vocabulary.I thought so,too.But my difficulty with E to E dictionary and I suppose many will agree , is that when you look something up in it, you will frequently find another unknown word in its definition and then, you look that unknown word up in the dictionary, then again you find another unknown word and such burden goes on and on and at the end of the day, you end up getting circulated within the pages of the dictionary and you never get back home :-) :-) .I think it's because E to E dictionaries are designed to clarify its words as best as they could and as if they somehow do not consider vocabulary range that they use to explain words.I think that's a big mistake because we are using dictionary simply because we do not have sufficient vocabulary and if we have such, we wouldn't use a dictionary.So, the way E to E dictionary is designed contradicts its own purpose which I would call the flaw of E to E dictionary.The time I noticed it is only when I watch youtube english lessons where native speakers teach new vocabulary and when I think of our mothers when we asked some new vocabulary of our own mother tounge language when we were young.They_native speakers and our parents do the same thing! They try their best to explain us only using simple vocabulary that they know very well that we will understand very well.As I came to realize the difference between E to E dictionary and the beauty of nature which seems reckless and chaotic but really very systematic, I know how to learn much better than I did in the past.I listen to my own heart, not to what other people suggest.I liberated myself from stereotypes.Sometimes, what majority of people say good would not be good for you.It could be wrong.Think outside the box.Majority cannot be the truth all the time.As I look back in retrospect of how our mothers taught me new vocabulary of my own mothertongue(She explains everything using vocabulary that she is sure that we will understand and she steps further and further very systematically and now we are grownups and we have reached equal vocabulary as hers),I know very well how to apply that method in my language class.I hope E to E dictionaries will look into this in the future.That would be a great help
