Afflicted with glossophilia? Fear not word mavens, we have two apps for you that we highly recommend, both of which are now Mango-ready and rich with features. Bonus? Both are free.
ArkWords (see earlier coverage) is a free dictionary app that allows you to look up words, use a thesaurus and translate words/phrases uing Bing. Our favorite feature though is the 'Word of the Day' which allows you see multiple definitions, hear how it sounds, look it up in a thesaurus and share using WP7's social network integration. On top of that, it has a Live Tile that displays the word of the day and the app itself has two color schemes, including all-black for AMOLED devices. The app is not only free but ad-free as well, making it a rare bird. There's nothing to not like here, folks.
Urban Dictionary 7 has been around for awhile and just hit version 2.0. Think of it as a dictionary app but for hot buzz words on the internet--we're talking the cutting edge of slang and colloquialisms, often boarding on the NSFW side. They're also hilarious. While the app is not "official" it might as well be as the developer, Social Ebola, has been churning out regular updates for this app for a long time time. The Mango version adds some slick animation, fast-app switching, various new options, fixes and a new feature called Urban Zen. Urban Zen pairs terms from Urban Dictionary with related Bing images in an elegant slide-show format--indeed it is very relaxing with the transitions, but you'll be chuckling at the definitions and photos. So stay hip and cool with this little guy.
ArkWords can be found for free in the Marketplace here and Urban Dictionary 7 comes in a free, ad-supported version here or an ad-free edition for $1.99 here. We don't care for ads on our top apps and use this everyday, so we've opted for the $1.99 version, but the choice is yours.
