the.com/riser
the quiet step that makes you taller without asking you to move.
means A riser is the vertical part of a stair step (or any vertical element that lifts something up — a platform, a pipe, the height a thing gains).
from From the verb 'rise,' which goes all the way back to Old English 'risan,' meaning to get up or ascend — a word with deep Germanic roots (a cousin of Old Norse 'risa' and Dutch 'rijzen'). Add the agent suffix '-er,' the same one that turns 'work' into 'worker,' and you get 'riser': literally the thing that rises. Builders borrowed it for the upright face of a stair, the part that does the lifting while the tread does the standing.
