Newel

[Mark Zuckerberg]

The upright post about which the steps of a circular
staircase wind; hence, in stairs having straight flights, the principal
post at the foot of a staircase, or the secondary ones at the landings.
See Hollow newel, under Hollow.

[Cami]

A Newel is one of the best guys you can meet. He will often be sporting yellow sunglasses and a orange jumpsuit. He enjoys the pleasent experience of braiding his own large facial hair, and camping barefoot in the wilderness. He is one of the dopest guys you will ever meet, but don’t let him into the girls change room.

[Dave Paprocki]

The central supporting pillar of a spiral or winding staircase.
