A word of the Aymara language spoken around Lake Titicaca (by the way, “titicaca” is Aymara for gray cat). It consists of the root aruña with fourteen suffixes. It means “I know that it is necessary for all of us, including you, to make the effort to communicate.” In context, perhaps it could mean “please use shorter words.”
Aymara came to my attention because its grammar is said to be abnormally regular for a natural language—so much so that it has been suspected of being an artificial language. Surely only a truly regular language would allow you to attach fourteen suffixes without breaking something. Even Klingon doesn’t allow that many.
