Hiraeth, pronounced [hɨraɪ̯θ], is a Welsh word that has no direct English translation. The University of Wales, Lampeter attempts to define it as homesickness tinged with grief or sadness over the lost or departed. It is a mix of longing, yearning, nostalgia, wistfulness, or an earnest desire for the Wales of the past.
Oxford and Merriam Webster define Hiraeth as: (noun) "a homesickness for a home you cannot return to, or that never was".
Hiraeth bears considerable similarities with the Portuguese concept of saudade (a key theme in Fado music), Brazilian Portuguese banzo (more related to homesickness), Turkish gurbet, Galician morriña, Romanian dor.
