(名詞) 居住地環境遭到重大破壞或發生重大改變所引起的憂傷或憂鬱。

據創造這個字的澳洲哲學家 Glenn Albrecht 表示,solastalgia 是由拉丁字 solacium (comfort:舒適;安慰) 和希臘文字尾 -algia (pain:痛苦) 拼綴而成。別懷疑! 現在確已允許將拉丁字和希臘字結合成另外的字。

Whereas nostalgia is homesickness for a place, solastalgia is a yearning for the way a loved place used to be.
—Des Houghton, "Pain has a brand new label," The Courier Mail, February 27, 2010

In a 2004 essay, [Albrecht] coined a term to describe it: 'solastalgia,' ... which he defined as 'the pain experienced when there is recognition that the place where one resides and that one loves is under immediate assault . . . a form of homesickness one gets when one is still at 'home.' '... In the past five years, the word 'solastalgia' has appeared in media outlets as disparate as Wired, The Daily News in Sri Lanka and Andrew Sullivan's popular political blog, The Daily Dish. In September, the British trip-hop duo Zero 7 released an instrumental track titled 'solastalgia,' and in 2008 Jukeen, a Slovenian recording artist, used the word as an album title. 'Solastalgia' has been used to describe the experiences of Canadian Inuit communities coping with the effects of rising temperatures; Ghanaian subsistence farmers faced with changes in rainfall patterns; and refugees returning to New Orleans after Katrina.
