Here are some other ways to interpret "coed by room":
* Mixed-gender roommates: In a "coed by room" arrangement, roommates can be of either gender. This could mean two female roommates, two male roommates, or one male and one female roommate.
* Shared living spaces: The term typically refers to shared living spaces within a larger residence, such as a dorm or apartment building. The rooms themselves are coed, but the building may still have separate facilities for men and women (e.g., bathrooms).
It's important to remember that "coed by room" doesn't necessarily mean that *all* rooms in a building are mixed-gender. There may be some designated male-only or female-only rooms, depending on the specific housing arrangements.
