Shit Americans Say

Lol. Kids spend months studying phonics in grade school because brit english resorts to multiple vowel combinations to express different vowels. https://www.englishradar.com/english-pronunciation/english-vowel-sounds/

Consonants are even worse, in many cases there is no way to know how to pronounce a word just by its letters, you have to know its pronunciation already. In general there are many rules and tons of exceptions. GH sometimes is pronounced F, while S is sometimes pronounced SH. Why? When? No real guidelines there.

Some of these rules have been simplified in american english, so for instance colour became color. That's a good thing because the only real argument against it is preserving etymological roots, which nobody gives a fuck about.
