I explained this when Chii's true name was revealed back a few dozen chapters ago.
While 연리 is composed of characters that are pronounced "Yeon" and then "Ri," when you put the two of them together, that's NOT how they're pronounced. There is a Korean dynasty known as Silla, which is spelled 신라. This would literally be pronounced "Shin" and then "Ra" but that's not how it's actually pronounced. Koreans pronounce it "Silla" as in "Sheila." When you get an ending consonant and a beginning consonant in sequence, the sounds can change. Kinda like how in French, when you get two vowels together, you end up changing the words. Eg: te aime into t'aime.
You're welcome for the update. I hope my explanation makes sense.
Edit: Wait, how do you even get Yeolli from 옐리? That would spell "Yelly." Where are you getting your information from? This is just factually wrong.
