What is a "sojourn"?

A "sojourn" refers specifically to a temporary stay in a place, often for a short period of time. This term conveys the idea of living or residing somewhere temporarily, rather than establishing a long-term home or permanent residence. The essence of a sojourn is that it is not intended to be permanent; instead, it reflects the idea of visiting or residing in a location for a limited duration before moving on.

The other options imply different meanings: a long-term residence signifies a permanent or lengthy stay, which contradicts the nature of a sojourn. A planned vacation typically suggests a leisure trip but does not encompass the broader meaning of temporary residing, often including aspects of rest or travel. A permanent abode indicates a fixed and unchanging place of living, completely at odds with the concept of a fleeting visit that a sojourn represents.
