okay so this is what i learned on why the word rural sucks, science supported:
when you write out the word rural by sound, it's just "rrl."
the english "r" sound is really unique. there's a symbol that we use for it in the phonetic alphabet, but it's not a true representation because the sound is actually made in like three different places in your mouth
so we take this sound that's already difficult to make with your tongue in a stupid place in a stupid way and we say it twice in a row. you gotta say it two times, you can't just squish them together or it's not the word rural. but we have a super weak vowel between the two r sounds so you don't even get any reprieve between the two r sounds
then we get to the l sound. because fuck vowel sounds in this word. we skip them. fuck vowels (not actually, vowels are really great and english loves those mfs). there are two different kinds of l's in english. one that's made with your tongue all the way up by your teeth (like in "light") and one that's further back in your mouth. the tip of your tongue is a little further back and you gotta make this weird shape with the back of your tongue to get the sound to move around the right way.
the word rural is three nasty ass sounds that are made from the back of your mouth, all back to back, with no reprieve between them
