At qepHom 2023, we learned some words for whistles. Okrand just gave me some additions on their usage. Most of it basically was clear, but it's good to have a definite response: - These ship- or factory-type whistles cannot be "played" by a person. They're powered by some sort of energy (steam, electricity, whatever). - You can use {SuS} if you're playing a {mu'vIb}, and {'uq} is if there's no instrument/implement involved (except maybe your fingers). - The verb to activate a wall-mounted device is {chu'} (not {SuS}). This is added to the Klingon Language wiki: https://klingon.wiki/En/Whistle The full message, include my questions, can be found here: https://qephom.de/e/message_from_maltz_231215_whistles.html -- Lieven L.
