Although I think word culling is sad, I can unfortunately see the purpose. There will always be texts in which you can read the more ‘old-fashioned’ words and the internet for translating the more obscure. Dictionaries can only hold so much, however, and language must progress. I occasionally encounter 19th century deeds in my day job and am awed by the volume of words used to say the simplest thing! It is elegant and charming but by golly is it hard to make sense of!
