Want to learn a new word? This is the best way to do it.

All it takes is about 160 repetitions within 14 minutes.
Neuroscientists at the University of Cambridge recently found that it technically takes less than fifteen minutes to learn a new word, given enough aural repetitions.
Not only that, but you do not even have to speak the word or think about it at all!
All it takes is a bit of passive listening on the part of the learner - your brain will automatically work on its own to form a network of neurons devoted to remembering that one word.
This task is quite difficult for the mind at first, but towards the end of the 14-minute period, the new memory traces will be nearly identical to that of any other word in your prexisting lexicon!
