In case you doubted that it’s a hard language to master, here’s a video that demonstrates the quagmire through which English learners must wade. In this short film, Aaron Alon shows what happens when you apply consistent vowel-sound rules to English. The result is something that sounds like a version of Old English — sort of familiar, but often difficult to decode. Run through the video once and you’ll gain a new appreciation of the tough work that English learners take on.
