Some time ago, I provided a helpful definition. At the time I neglected to include other interesting aspects about its usage. For example, from the intro at Wikipedia, there’s this:
In 1808 the poet and essayist Robert Southey used the word to describe a desire (particularly by the English) to leave home and travel. Southey’s usage as a synonym for wanderlust was picked up by other nineteenth century writers.
Roger Scruton’s usage, mentioned in the original link, was the first in a political context.
SAS (Scandinavian Airlines) has produced a textbook example of the term oikophobia which conveniently operates under both definitions above. It has caused quite an uproar, so the link here is a google search term.
