It seems to me that a lot of basic philosophy is about definitions of abstract words. So, Plato might have asked what courage or love are, Enlightenment philosophers might have been interested in what freedom is, more modern philosophers might inquire what science is.
I guess I'd like to ask a two-part question.
The first is what the difference is between the sort of definition a philosopher might give and the sort of definition a lexicographer might give. What are philosophers doing that lexicographers aren't?
The second is, if it's fair to say that philosophers are interested in defining abstract words, well, is the task inevitably culturally and temporally specific? I mean, does the Latin word "pulchritudo" really mean the same thing as the English word "beauty"? Does the Greek "aletheia" really mean the same thing as "truth"? And couldn't the meaning of a word like "freedom" change over time?
