In a housing context, what does the abbreviation WG stand for?

In the context of housing, the abbreviation WG commonly stands for "houseshare." This term is often used in countries like Germany to refer to shared living arrangements where multiple individuals rent a home or apartment together, typically sharing common areas such as the kitchen, living room, and bathroom while having their own private bedrooms. Housesharing can promote a sense of community and can be a more affordable way for individuals to live in urban areas where housing costs are typically high.

While the other terms listed might have their own meanings in different contexts, they do not relate specifically to housing arrangements in the same way that "houseshare" does. For instance, "work group" refers to a team of people working together on a project, "wage gain" pertains to income increases, and "welcome group" does not have a standard meaning associated with shared living. Therefore, "houseshare" is the most contextually relevant term in this instance.
