It has been suggested - although I am unsure if there is strong evidence - that the word "bear" is a euphemism along these lines, meaning "brown one" for the since-forgotten original name for the animal, as it was allegedly believed to be either too frightful to say aloud, or would summon a bear.
While it's conceivable (consider phrases such as "speak of the devil and he shall appear" and similar phrases in other languages), I would also say the etymology of names for things are often at the same level as "brown one":
• Horse, ultimately from Proto-Indo-European *ḱers-, “to run”
• Planet, from Ancient Greek πλανήτης (planḗtēs), “wanderer”
• Lots of Latin-derived words, companion (bread together), conspire (breathe together), transgression (step across), etc.
• Hamburger the food named after the city of Hamburg, where "burg" means "castle", because it had a castle
• My forename means "son of the right/south" or "son of days", my family name means "wheat field/clearing" (in a different language); where "wheat" itself comes from Proto-Germanic, from *hwītaz (“white”) and the "ley" part from Proto-Indo-European *lówkos (“clearing”), derived from *lewk- (“bright”), and *lewk- also gives all these derived terms even just in English:
Oh! Cape of Good Hope was renamed that way when portuguese mariners discovered they could go around the areas more susceptible to "freak waves".
This is a problem even today, some have said it is due to hotter currents coming from the Indian ocean meeting the cold Atlantic. But the judge is still out on that one.
