Simple: state your favorite word in the English or possibly another language and say why you like it or love it so much; the sound? The meaning?
My favorite word, I have to say, is the Japanese word SHINKA! It means "evolve" and is used in the anime Digimon.
i.e. Renamon SHINKA....Kyuubimon!
My favorite word in English, is, fittingly enough, the word DIGIVOLVE, which was used in the Digimon dub.
i.e. Renamon, DIGIVOLVE to...Kyuubimon!
