fernweh
noun·/ˈfɛrn.veɪ/
A longing for far-off places, an ache for distance itself, as if the horizon were a summons rather than a line. Where wanderlust can sound cheerful, fernweh often carries a sweeter pain: homesickness turned inside out, pointed toward elsewhere.
On quiet afternoons, fernweh would take him by the throat, and even the map on his wall seemed to rustle.
Etymology
Borrowed from German Fernweh, literally “far-sickness,” formed on the model of Heimweh “homesickness” (fern “far” + Weh “pain, woe”). The coinage is modern, but the feeling is old: restlessness given a diagnostic name.
