I prefer this over French-English translation dictionaries because it's more thorough and gives example usages in French. The drawback is that you can't enter the English word and expect its French counterpart to appear.For the record; hubris is from ancient Greek. It's French counterpart; though similar in meaning, developed independently; is orgueil: "Présomption, estime exagérée, amour excessif de soi-même, qui fait que l'on est persuadé de sa propre excellence, que l'on se juge supérieur aux autres." -Trésor de la Langue Française informatisé

This is an amazing app, especially for the price. You pay through the nose for the Robert dictionary, but just a couple bucks for this one, and it's every bit as good.

it is a little complicated for me, i need something practical

The first word I searched for was "hubris", arguably not a very complicated word. Well, it is not in this dictionary! I am sure that there are many more examples of important words that are missing. If you need a dictionary as a tool for your research or your writing projects, do not use this one!
