I never knew that there was a word that covered the meaning of what I've always felt in my heart. I wonder if we could expand it a little bit to make it mean "a home that'll never exist"? Because then it may be linked to traveling.
Hiraeth. In Welsh: a homesickness for a home to which you cannot return, a home which maybe never was, the nostalgia, the yearning, the grief for the lost places of your past. It has no direct translation in English.
I recently came across a wonderful Cymraeg blog called The Welsh Word of the Day, where you can see different words in Welsh, along with the translation and pronunciation in English. You may even submit a word or words for translation–just words, however, not sentences or quotes, because that would entail a HUGE workload for the site admin, Mathew Hayes. He’s providing a great way for anyone with Welsh or Celtic heritage in general to learn a bit of the beautiful Welsh language.
