Definition

1. Noun (plural: nodi or nodes):
   • A knot or point of intersection: In anatomy, botany, or general usage, "nodi" refers to points where parts join or intersect, often forming a thickened or knotted structure. For example, in a plant stem, a node is where leaves grow; in a network, it is a connection point.
   • A central or critical point: In figurative language, "nodi" can mean a crucial or pivotal aspect of a problem or issue, akin to a "knot" that must be untied.

Usage Examples
