Discussion: why don't we use English dictionary like OxFord Dictionary?

[frodo821]

I think the idea of the basic design of this library is light-weight and working roughly. But one of the most important functions, which is pluralizing/singularizing words is far worse than we expected.

Thus I'm wondering why don't you use some English dictionaries like Oxford Dictionary. My think may be irrelevant, but I assumed that someone should suggest the thought.
