Language limitation, the death of philosophy

Well, philosophy started as 'love wisdom', after science separated from it, I think there's pretty much nothing useful left. One reason is that how we can use our language to communicate something as precise as 'philophy' definitions. When I say 'apple', you can understand what it means as simple as 'apple'. But what exactly do I mean by 'apple' at the precise point and time? Maybe apple is easy to understand between us, what about 'soul', 'spirit', 'existence'? Do you think we can communicate effectively on the preciseness of those words? I think not.
