Drill'em all

I've just noticed, that it would be a very useful program - the program which allows to learn as much of words-synonyms as it possible, on a particular subject. For example, all the kinda "good" epithets like "good", "nice", "pleasing", "pleasant" etc, and with division by target noun - human, thing or phenomenon (something else?). It resembles the "activator" feature, but ought to be more friendly to user and aimed on learning only.

Interestingly, what kind of interface and conception of interaction could be used for such software. Has someone got an idea?
