Well, we won’t sugarcoat it, It’s a tongue-twisting word, especially the ö. Starting with the ‘J’ at the front, pronounce this as a ‘Y’. Then if you think of ea in earth – you can call it Yearth, Yeard - you’re on the right track. Don’t worry about getting it wrong, we’re really not that particular about how you pronounce it.
You know, the d is actually really old and derives from the letter edh or eð. It was used in Old English, Middle English, Icelandic and Faroese. In the Middle Ages, we also used the letter in Scandinavia where it was eventually replaced with dh and later d, as we know today. You can still find the old edh letter on Faroese and Icelandic keyboards.
