tầng

1. (architecture) story; floor

   tầng 1 ― the first floor (either (Northern Vietnam) the ground floor, or (Southern Vietnam) the floor immediately above it)

   tầng trệt ― (Southern Vietnam) the ground floor

   tầng hầm ― an underground level

   tầng lửng ― a full-fledged mezzanine, as opposed to a gác lửng which is just a platform used in small flats

2. (by extension) vertical level

   giường hai tầng ― double bunk bed

   18 tầng địa ngục ― 18 levels of hell

• In Southern Vietnamese, the ground floor is called trệt and each floor above it is a lầu numbered from lầu 1. By contrast, in Northern and Central Vietnamese, floors are called tầng, the ground floor is numbered as tầng 1, and tầng 0 technically refers to a crawl space.
