I'm trying to help people express themselves better, where they start with a thought or feeling inside their head, and then find the best word that matches it, before adding distinctive qualities. So in a sense, they are starting with their own definition/description of what they are thinking and feeling...until they find the word that matches it. Then they can type that into search engines like OneLook to see if they can find better/more concise ways to express themselves.
This seems especially helpful with words like 'normal' that have more than one meaning--wordnet provides two that match so closely, there's no way of knowing which one is intended most of the time; one means to 'conform' and the other means 'near average.' So, helping people 'define' the meanings of the words they use seems like a very important skill to me, and the 'find the closest word and then add distinctive qualities' seems reasonable. I'm asking because I'm clearly not a lexicographer....
