This is a common feature of primitive languages (including Proto-Uralic, which Finnish and Hungarian are descended from, as well as possibly Proto-Indo-European according to this paper -- though it's best known from Australian languages), but there's no way Salazar Slytherin would have neglected to put a full system of numerals into a language designed to be used for trustworthily planning and executing plots.
What's a full system of numerals? Even in Proto-Uralic, you could say ‘four and one’, and a human mind would understand that (whereas rabbits start getting confused, if I remember my appendix correctly). Conversely, in English, we don't have a word for 21; we just say ‘twenty and one’ (abbreviating the ‘and’ to a hyphen, while in French and German the ‘and’ remains).
Two new short chapters! Since the next one is coming tomorrow and we know it'll be short, let's use one thread for both.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 105 (and chapter 106, once it comes out tomorrow). EDIT: based on Alsadius' comment about thread creation for MOR chapters, let's also use this thread for chapter 107 (and future chapters until this nears 500 comments) unless someone objects to doing so. Given that this is the final arc we're talking about, thread titles should be updated to indicate chapters covered.
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
