Not long ago, I had a conversation with a gentleman working at my building. I asked him if he lived in the building and he said "No I live in a home."
I thought that was a strange wording, but I understood. I may have heard this phrasing once or twice before (in the Midwest United States). Home is a fancy synonym for house. People in America often talk about "finding a home", and usually mean a single-family house. But my understanding of the word home has always been just a place where you live. That is the first result on Google, which doesn't mention "house". Merriam-Webster does include house as a synonym in definition 1b.
Just today I was talking to someone online, not local, about apartment problems, and I used the word home for apartment, and they said something like "No it's different for people in homes."
So it wasn't my imagination or just a weird quirk of the midwest. This is considered acceptable usage in English, although maybe not common? When and where did this specific sense of the word "home" originate? Is it a recent construct or something I've just not noticed most of my life?
