If we consult the Bible, Genesis 11: 1-9, we find the whole world had a common language
which moved eastward with Earthlings to the plains of Shinar, where they settled. They built a tall tower to celebrate, but used materials --brick instead of stone and tar instead of mortar-- which offended the Almighty and other investors who accused humans of hubris and inferior materials then responded by collapsing the tower and confounding the languages of the planet.The Welsh were suddenly overwhelmed with consonants while the Hawaiians got stuck with all the vowels. It was around this historical calamity that vowels became a fungible medium of exchange.
My own ancestors came from Portugal in the 1800s with family names that had scads of vowels, like Azevedo, and were encouraged to sell them in exchange for prosperity in the new world --they became the Browns.
But all the brave abbreviations various families made fade faster into history when we run across a weather report like Liam Dutton's. He ran through the 60(+or-) letters of a Welsh town with accuracy and nonchalance. He is my hero.
