Can you please define "snapshot" and "subvolume"?

I have difficulties grabbing these two concepts.

As far as I can tell, a snapshot is an instant, synchronized,
photography of the filesystem at a given point in time; a subvolume is
a "subroot" to a btrfs filesystem.

While I fully understand (and use) the purpose of snapshots, I don't
quite fathom the use case for subvolumes, apart from btrfs-convert...
Why has btrfs grown such a feature in the first place? Can someone
give me a use case for them?
