whenever the show refers to species as “humanoid” or “not humanoid” - I tend to make an assumption that it’s a universal translator thing, because why would other species also refer to themselves as humanoid???

soooo:

 - Julian learns Kardasi and discovers that the Cardassians have been saying the equivalent of “Cardassian-lite” the entire time (essentially “like Cardassians, but worse” folded into one word)

- Benjamin realises that Bajorans call non-Bajoran bipedal beings the “acceptably unfaithful” (it sounds better in Bajoran)

- Klingons say “weaker than Klingons.” B’Elanna takes offence, Worf is like “this is reasonable” (B’Elanna and Worf arguing Klingon linguistics based on their own relationships to tho)

- Betazoids and Vulcans independently of one another coming to the conclusion that they’ll call the other species “the talkies” (Betazoids for obvious reasons, Vulcans because humans just talk too much for no reason???)

- Dax once told Benjamin that the Trill phrase is roughly the same as “why don’t they have spots?” based on the alleged first words uttered when they encountered spotless species

- Ferengi call other species “fools.” Occasionally also “tall.”
