There is a welsh word ‘Hiraeth’ (pronounced he-reyeth) that describes a nuanced kind of homesickness. It is not limited to only missing a place or a home. Instead it has a multi-layered meaning, in that it translates to a kind of unattainable longing for a place, person or time that is unreachable and perhaps doesn’t even exist. It is not inherently negative, as it also suggests a place of comfort that you can return to. It combines elements of longing, nostalgia and homesickness.
