The explanation I gave was very english speaking oriented so I wanted to explain it like the dictionary for people who dont know english like a native. The live under a rock part is just me being cynical because there are lots of comments asking the same thing so I'm surprised so many people instantly comment before reading other comments for example or just google it. That's about it. I know it was best expressed.
For some reason people dont know what cphabiting means... I will assume you live under a rock under your house lol. It probably comes from the word inhabit, which means to 'live in' a place. The prefix Co- means 'together' so they are essentially living together as a couple~ Guys, please tell me you knew "inhabited" exists... if you grew up with english
