Noun. From Welsh.
“A longing feeling, similar to homesickness, that can involve people or locations”
This is an amazing word, not only because of its potential range of meanings, but it’s also a Welsh word that is pretty much pronounced how it sounds!
The attempted translation I gave above was deliberately vague, because there seems to be quite a big variation over what it really means. For instance, some refer to it as a longing for a physical location, even if that location doesn’t actually exist. Others, including the University of Wales, define it as a kind of homesickness and/or grief associated with the lost or departed.
However, there’s a far more artistic approach to its definition and true meaning here. As to whether it’s the meaning intended, I have no idea!
