In Cydia Store you can find a lot of tweaks that can remove from my opinion that useless page called Spotlight Search, but what if you can give another meaning to that nonsense. Well with what I am about to present you can transform Spotlight into a Dictionary. Yes you heard it right; you will have the possibility to lock up a definition of a word. Maybe for some of you this is useless too. Is it useless when you hear a new word and to avoid any embarrassment you rely to something like this? The answer is simple, no. It is good to improve yourself than to stay ignorant.
Installation of SpotDefine is very simple, so does the functionality. You just simple input the word in the Spotlight field and after the search is complete you will be greeted with the definition and much more information related to that word.
If you want to have a Dictionary instead of the usual Spotlight functionality head to Cydia and download SpotDefine from the BigBoss repo this tweak for free.
