Etymology

node = nod<knot> + e (silent)

  • nod (from Latin nodus "knot")
  • e (silent letter, no semantic value; preserves spelling from Latin)

Etymology Origin:
The word "node" traces back to Latin nodus, meaning "knot," reflecting its original sense of a physical junction or swelling. Over time, it expanded metaphorically to describe intersections in networks (e.g., botany, computing), retaining the core idea of connection points. The silent "e" is a vestige of its Latin spelling.
