Is it correct to use the word "roommate" to say the person who shares the same office room?
People around me says that the word "roommate" is used when to say the person who shares the same living room like an apartment. If I look at the definition from merriam-webster, it says that "Define roommate: one of two or more persons sharing the same room or living quarters". If the "room" in this definition is not limited to living room, I think I can use the word "roommate" to say the person who shares the same office room.
Office room here is small room that can accommodate 3 or 4 persons.
