On "mute" L's. The Spanish. The number of places I have been where there are clearly L's in the place name but none are pronounced in Spain tops most other "L's omissions".
LIterally went paragliding in "Montellano". Pronounced. "Monti-ano."
There was another one, I'll butcher the spelling, but Collolyte. Pronounced like Coyote.
Yeah, that’s not a “mute” L.
It’s that the double-L (which historically was treated as a separate letter in the alphabet!) is the “y” sound (almost identical to the initial consonant of “yes”) in most dialects of Spanish. Spanish has both the letter
ll and the letter
y, and they sound the same because
ll originally represented a different sound, but in most dialects they merged to the “y” sound.
Some regional dialects of Spanish retain the original pronunciation, and in others it changed to different sounds. (Among the sounds is something approximating the English “j” sound, as Aldo22 said.) See
https://en.wikipedia.org/wiki/Yeísmo.
But what
ll never was, nor is, is silent.
(I grew up bilingual Spanish-English as a kid, and my Guatemalan dialect puts me among the ~90% of Spanish speakers for whom
ll and
y are identical.)
