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[1] for the Wales of the past.[2]

Oxford and Merriam Webster define Hiraeth as: (noun) "a homesickness for a home you cannot return to, or a longing for a home that never was".
