Definition of flatmate

The term "flatmate" is a commonly used word in British English to refer to a roommate or a co-renter sharing a dwelling unit, typically an apartment or a flat. Its origin can be traced back to the early 20th century, when rental properties in urban areas started becoming more popular in the United Kingdom. The word "flat" is a reference to a self-contained dwelling unit, usually found in a multi-story building, which is commonly known as an apartment in American English. The term "mate" in this context refers to a companion, friend, or a partner. The word "flatmate" is a combination of both words, indicating a roommate who shares a flat or an apartment. The word has become quite popular and widely used in the British English-speaking world, especially in countries such as Australia, New Zealand, and South Africa, where it is frequently used to replace the term "roommate". While some people argue that the term "flatmate" creates confusion because it can also refer to a person who shares an entire property, as opposed to a single apartment, the majority of British English speakers consider it as a basic and commonly understood term. Its usage is particularly prevalent in contexts where individuals share the responsibility of maintaining and paying for the rent of a shared dwelling unit.
