komitato

Komitato sits unusually high in the Esperanto frequency lists for a bureaucratic noun, and the reason is simply that the movement has always run on committees. A century of association minutes, congress reports and magazine notices has pushed it past plenty of everyday words. Komitatano, a committee member, is standard organisational usage and shows the -an- suffix doing its job. Beyond that the word is unremarkable and behaves exactly as English does, taking de for what it governs and pri for what it discusses.
