Floor sagging due to cantilever support wall.
These interior walls have defined floor plans for centuries but starting in the 1950s when the open floor plan style became popular many of these walls segmenting the house fell into disfavor.
Foundation issues deteriorating wood supports especially sills which rest on the foundation footer improperly installed joists or sub floors and other issues can all cause a floor to slope or sag.

For example you could have a bay window sitting on the end of a 2 foot cantilever and this would be considered nonbearing because typically a header is back at the main wall line to support any loads from above.
