In a staircase, a large baluster or post used to anchor the handrail is known as ______.
🔬 Understanding the Balustrade System
The question focuses on identifying a key component of the balustrade—the safety barrier of the staircase. This system consists of a handrail, balusters (or spindles), and larger posts at key points for structural stability.
Newel (or Newel Post): This is the primary structural post of the balustrade. It is a large, vertical member placed at the beginning, end, and at any change in direction of a flight of stairs. Its main function is to anchor the handrail and provide rigidity to the entire railing system.
Without newel posts, the handrail and balusters would lack the necessary strength to function as a safe barrier.
⚖️ Detailed Analysis of the Options
Let's examine each term to pinpoint the correct component.
(d) Newel
Why it's correct: As defined, the newel post is the large, anchoring post for the handrail at the ends of a flight. It is the correct answer.
(a) Wall string
Why it's incorrect: A stringer (or string) is the inclined beam that supports the steps. A wall string is a stringer that is fixed directly against a wall.
(b) Nosing
Why it's incorrect: The nosing is the front edge of the tread that projects slightly over the riser below. It is part of the step, not the railing system.
(c) Finial
Why it's incorrect: A finial, often called a newel cap, is a decorative element placed on top of a newel post. It is an ornamental piece, not the structural post itself.

The following image and definitions cover the essential parts of a typical staircase.
- Step: The part of a stair that permits ascent or descent, consisting of a tread and a riser.
- Tread: The upper horizontal part of a step where the foot is placed.
- Riser: The vertical part of a step.
- Landing: A level platform between flights or at the end of a staircase.
- Flight: An unbroken series of steps between landings.
- Rise: The vertical distance between two consecutive treads.
- Going: The horizontal distance between two consecutive risers.
- Nosing: The projecting edge of the tread over the riser.
- Scotia: A concave molding under the nosing for support and decoration.
- Soffit: The underside of the staircase.
- Pitch or Slope: The angle of the staircase with the horizontal.
- Strings (Stringers): The sloping members that support the ends of the steps.
- Newel Post: The large vertical post at the ends of flights that anchors the handrail.
- Baluster: The smaller vertical members that support the handrail between newel posts.
- Handrail: The rail that runs along the top of the balusters, providing a handhold.
- Headroom: The clear vertical height from the nosing of a step to the ceiling or soffit above.
