I love reading on my Kindle (3rd generation keyboard). I always thought the ability to create your own vocabulary collection to learn new words would be a good idea and I’m glad they’ve added it in their latest software release (not available on my old Kindle however). Here is the feedback email I sent on Monday, Jul 26, 2010 at 1:23 PM:

Hi,

I don’t know if it is true, but I guess one of Kindle’s mission could be to promote reading. If we assume this is the case, then “expanding vocabularies” would be a sub-mission. That is, helping people learn new words.

The built-in dictionary is gold for doing exactly this! I would add a suggestion which I think is kind of nice:

Allow people to not only look up the definition of words, but to construct a list of words that they want to study and remember (learn).

It is easy to look up a word, understand its meaning, but then forget both the word and its meaning. While the dictionary is active, pressing a dedicated button on the keyboard could add the word to a collection of words stored in a simple text file on the Kindle (one word per line). This file could be downloaded while the Kindle is connected to the computer, or read directly on the Kindle.

I guess the same thing could be done already by highlighting a word, but this is clumsy and far from ideal. In addition, the “word list” would be mixed up with highlighted passages.

This functionality could be sold by Amazon as a way to help people expand their vocabulary!

I believe the implementation would be quite simple, but the added value would be great.

Please let me know what you think of this idea.

Thanks,
