noun
stair
STAIR/stˈɛr/
A step in a connected series leading from one level to another.

Etymology
Old English stæger could name a staircase or flight of steps, not just one step. The modern singular sense narrows that larger arrangement to one member of the succession between levels.
In context
the fifth stair to the fourth stair or down to the third stair or the second stair or whatever
