Tolkien studied languages, so he would've understood and probably appreciated how often things are named purely based on what they do or their immediate aesthetic values. Language is all about communication after all. Sometimes that necessitates complexity, but it should always be as simple as possible without sacrificing nuance.
the vast majority of place names irl are just objective descriptors, optionally with that having been twisted through time.
Exeter means "castle on the river exe", starting as "esceancaster"; Aberdeen means "mouth of the river dee"; Amsterdam means "dam in the amstel"; Stockholm means roughly "log islet" as it started on the tiny central island which they put logs around.
And of course in germanic areas there's the very common "burg/borg", which just means that the place has a castle/fortification.
I was gonna make a snarky comment about how Treebeard has a cool Elvish name, then I looked it up and “Fangorn” literally means “Treebeard” in Sindarin 🤷♂️
Yeah but his original name really is unpronouceable because it would take literal days to spell out, if I remember correctly. So it's not completely unrealistic for others to want a shorter version. Like when Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu gets shortened to Taumata Hill in english.
In fairness, Mount Doom has multiple different names. Source: Finished the Silmarillion for the first time last night. :)
Orodruin, Amon Amarth, Mount Doom.
Mount Doom is also where the band Amon Amarth got their name from which is funny because they don't have any songs with Tolkienian fantasy and they're not really even huge Tolkien fans. It just sounded cool
I used to parrot the "created multiple languages, named the place Mount Doom" meme up until I started getting deeper into Tolkien lore. Now I'm the obnoxious one that points out all the other names for Mount Doom, as well as translating other "cooler" names to show that they're all similarly named (my favorite being Khazad Dum, or "Dwarf Hall", followed by Cirith Ungol, or "Spider Cleft").
