German doors feature a "lip" (known in the industry as a rebated or rabbeted edge) primarily for superior insulation, privacy, and noise reduction.
The doors swinging inwards means that it's much harder to pry them open with a crowbar or something similar since the frame is covering the neuralgic points towards the outside. Also, with a door swingin inwards it's easier to block it or slam it shut in case someone wants to force their way in.
The "lip" on the bottom of a door typically refers to either the seal attached to the bottom of the door panel or the raised frame on the floor.
In Europe, placing door knobs and handles in the center of the door—a common style in historic regions like the UK, France, and Spain—is primarily a design choice rooted in 18th-century classical architecture.
A door undercut is the gap or clearance between the bottom of the door and the bare floor or carpet. The purpose is to provide clearance for flooring so it can open and close easily, but also to ensure good air circulation throughout the property.

Modern Entry Doors Are Built for Energy Efficiency
Older homes often relied on storm doors and screen doors to add an extra layer of insulation. However, most new front doors are already highly insulated, making additional doors unnecessary.
A "sock on the doorknob" is a classic college or dorm room signal. It serves as a makeshift "do not disturb" sign to let roommates or family members know that someone is having intimate relations inside and that the door should not be opened.

Wrapping foil around doorknobs is often shared as a DIY home security hack to catch intruders.

However, security experts note that this is largely ineffective and not a reliable safety measure.
