If you're interested, I made a statistical evaluation of the Sindarin dictionary hosted at www.sindarin.de. There is some math involved and a Venn diagram. (Venn diagrams are cool.) It is available in both html and shiny pdf:

Tell me if you have any suggestions about what else could be evaluated (derivative endings for verbs and adjectives maybe?).
