Origin of node
First recorded in 1565–75, node is from the Latin word nōdus knot

Examples from the Web for node
The flying machine was the mysterious creation that Node had so often hinted at.
He assured Node that her tail would be the wonder of the world.
Alfred assured Node that he could be of even greater assistance.
While the machine was in course of construction Node had his own way in everything.
Node was evidently not sure in his mind that the flight would be successful.
- a knot, swelling, or knob
- the point on a plant stem from which the leaves or lateral branches grow
- physics a point at which the amplitude of one of the two kinds of displacement in a standing wave has zero or minimum value. Generally the other kind of displacement has its maximum value at this pointSee also standing wave Compare antinode
- Also called: crunode maths a point at which two branches of a curve intersect, each branch having a distinct tangent
- maths linguistics one of the objects of which a graph or a tree consists; vertex
- astronomy either of the two points at which the orbit of a body intersects the plane of the ecliptic. When the body moves from the south to the north side of the ecliptic, it passes the ascending node; moving from the north to the south side, it passes the descending node
- any natural bulge or swelling of a structure or part, such as those that occur along the course of a lymphatic vessel (lymph node)
- a finger joint or knuckle

Word Origin and History for node
early 15c., "a knot or lump," from Latin nodus "knot" (see net (n.)). Originally borrowed c.1400 in Latin form, meaning "lump in the flesh." Meaning "point of intersection" (originally of planetary orbits with the ecliptic) first recorded 1660s.

- Anatomy A small mass or lump of body tissue that either occurs naturally, as in the case of lymph nodes, or is a result of disease.
- A point on a stem where a leaf is or has been attached.
- A swelling or lump on a tree; a knob or knot.
- Physics A point or region of a vibrating or oscillating system, such as the standing wave of a vibrating guitar string, at which the amplitude of the vibration or oscillation is zero. Harmonic frequencies in oscillating systems always have nodes. Compare antinode.
- Either of the two points on the celestial sphere at which the path of a revolving body, such as the Moon, a planet, or a comet, intersects the ecliptic.♦ The point at which the body traverses from south of the ecliptic to north is the ascending node. The opposite point, when the body traverses the ecliptic from north to south, is the descending node.
- Either of the two points at which the orbit of an artificial satellite intersects the equatorial plane of the planet it is orbiting.
- Computer Science A computer or a peripheral that is connected to a network.
