Why this pair is hard
German and Dutch spell this glide with the letter j, so 'jet' can begin like 'yet'. Many Spanish varieties do the reverse, hardening y into a j, so 'yam' becomes 'jam'. Mandarin, Cantonese and Korean have no voiced affricate, so J loses its buzz and can flatten toward the glide.
