it's actually a due to a research field created/popularized by Tolkien

https://en.wikipedia.org/wiki/Phonaesthetics

all about studying pleasant sounding words, big pharma uses it for naming drugs. "Cellar door" was one of Tolkien's favorite phrases, you can see variations and modifications of it in many fantasy settings

>Tolkien, Lewis, and others have suggested that cellar door's auditory beauty becomes more apparent the more the word is dissociated from its literal meaning, for example, by using alternative spellings such as Selador, Selladore, Celador, Selidor

There's a related field, phonosemantics, about the inherent meaning of a word because of how it sounds. (Words which sound like what they should sound like are, I would guess, pleasing.) Onomatopoeia fall in this category: bang, crash, pow, glug-glug.

Teensy eensy tiny itty bitty little bit. All /e/ and /i/ front vowels. The mouth is literally closed up. Grand large vast ginormous expansive gargantuan. All /a/ back vowels. The mouth is literally relaxed and open. There are of course exceptions (big, small being notable) but English has a strong tendency in this way with size terms. Big = back and open vowel. Small = front and close vowel. This tendency isn't restricted to English; it shows up across languages in unrelated language families.

One of the classic linguistics experiments is Bouba and Kiki [1]. One of these shapes is called Bouba, and one is called Kiki. As you probably already instinctively know, the one on the right is Bouba, and the one on the left is Kiki. Arabic, Japanese, English, Swahili speakers all agree on this, with like 90% or greater concord across cultures being typical.

And one thing I noticed myself I haven't seen written about elsewhere. Take a look at the letter forms for how we write these sounds. In English: Bouba, Kiki. In Japanese: ボウバ and キキ. In Arabic: بوبا and كيكي. Bouba is written with round glyphs that enclose spaces. Kiki is written with sharp straight lines. Maybe that is just a coincidence. I haven't done a larger sampling than those three writing systems.

Other patterns tend to show up within a language, but not cross-linguistically, and are probably arbitrary associations formed simply because of existing patterns. For example with English:

* gl- : related to light -- glance, glare, glass, gleam, glimmer, glint, glisten, glitter, gloaming, gloom, gloss, glow

* sw- : related to a long movement - sway, sweep, swerve, swing, swipe, swirl, swoop, swoosh

The last three are very fun: swirl, swoop, swoosh. Swirl ends in -rl which literally curls (oh, there's that rl again) the tongue. A swoop ends with a stop consonant. Accordingly, it has more finality, suddenness, than swoosh. So: a bird swoops in to grab its prey. And a bird swooshes by, when it misses that prey.

I've noticed that too. It's like some form of synesthesia, where one sense (audio in this case) influences perception in another seemingly unrelated sense (visuals).

And, perhaps related, in addition to their regular meaning, a lot of things seem to also have an inherent symbolic value. Like going up/going down, on top/at the bottom, sharp/blunt, clear/foggy, etc.

I think that most people, when asked, would prefer going up to going down, even though they have to push against gravity.

Oh cool, so that is where Donnie Darko got it from ("the most beautiful word in the English language")

[misstuned]

There is, or was, a radio/TV company in Europe called Celador - I always wondered where the odd-sounding name came from.

[SamFold]

Also the name of the island where the dragons live in Ursula Leguin’s books. (Written Selidor)

[collaborative]

Also means jail keeper in Spanish
