What does nodal mean?
Nodal is chiefly an adjective meaning related to a node: a point that joins or organizes other elements. It can describe a physical or network junction, a central feature of a system, or a mathematical or scientific point with a special role. In graph theory and engineering, nodal points are the places at which connections meet or in which a function is zero. In physics, the term is especially associated with standing waves, whose nodal points have zero displacement. Figuratively, a nodal development, event, or feature is one that has an unusually strong effect on what follows. The word is more formal and technical than ordinary alternatives such as “key” or “central,” and is most natural in academic, scientific, and infrastructural contexts. It comes from Latin nodus, “knot,” which gives the word its long-standing association with points of connection and the structure they create.
Relating to or constituting a node; especially forming an important point in a network, system, or mathematical structure.
"The researchers focused on the nodal regions where changes in pressure accumulated."
Common in formal, technical, and scientific writing; “nodal point” is its most familiar fixed expression.
A node or nodal point, especially a point of connection or zero amplitude in a technical system.
"Each nodal was treated as a separate variable in the calculation."
The noun is uncommon outside specialized mathematical, scientific, and engineering contexts.
The plural is rare and occurs mainly in specialized technical writing.
"The model evaluates the electrical behavior of the nodals before assembly."
From the Latin for “knot,” nodal names the points where networks, waves, and mathematical structures meet—and where their behavior can hinge.

Where does nodal come from?
Nodal entered English in the early 17th century from Latin nodus, meaning “knot.” Its formation uses the Latin-derived suffix -al, producing an adjective associated with knots, junctions, or nodes. The same Latin source lies behind English words including node, nodule, and nodose.
