That one only works when the homeland is that beautiful.

I don't know. I mean it's not a longing for just a place, as I understand it. I am not even sure that hiraeth is necessarily longing for the beauty of a place or time. Hiraeth, it seems to me, could equally be a longing for the wordless Welsh expressions of emotion, or for rainy days, or damp, or a time that has passed, depending on where the bearer of the emotion is currently feeling it.

(I am not Welsh, but it has been described to me as an ever tightening elastic emotional rope that is anchored in a place and time that it might not be possible to go back to)
