This is a digital Ancient Greek - English lexicon based on the famous intermediate Liddell-Scott dictionary (1889-seventh edition) -
made available by Perseus
http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0058

It can be used as a Kindle dictionary and finds even inflected terms, which of course is a huge advantage when it comes to ancient Greek.
It has around 35,000 basic entries (i.e. not counting the inflected forms)

After transfering the file to your device, Kindle should instantly recognize it as a dictionary and, upon opening any e-book, allow you to choose it as default dictionary for the e-book in question.
