Roommate
A "roommate" is a person with whom one shares a living space, typically an apartment or house. Roommates often split the costs of rent, utilities, and other household expenses, making living arrangements more affordable. They may also share responsibilities for cleaning and maintaining the shared areas of their home.
Roommates can be friends, acquaintances, or even strangers who meet through platforms like roommate-finding websites or college housing offices. Living with a roommate can foster social connections and provide companionship, but it may also require effective communication and compromise to manage differing lifestyles and habits.
