At
https://www.kli.org/chabal/ they now have a wishlist of new Klingon words you'd like Marc Okrand to coin.
I registered today as a guest. Guests are allowed two word requests each, and I requested words for
headphones and
disorder, disability, syndrome, condition. You may also register as a 1-year member, 5-year member, 10-year member, or lifetime member, meaning you'll get to view more parts of the site and request more words.
All registered members -- even guests -- may upvote or downvote other people's word requests. Especially recommended by He'me'HeqIS are "adverb(ial)", "blink", "fish (verb)", "freckle", "friendship", "gay/lesbian/bisexual/transgender", "monopoly", "parent", "teen", "trillion", "tumor", and "twin". Adding "mercury", "aluminum", "tin", and "zinc" seems like uncontroversial common sense (and I see that all four of these element words will apparently make it). Some words are apparently redundant, on the other hand, and are getting majorly borked by the voters!
If you register with that site, let me know and I'll check out your requests!
