Why this word

cause

Causality refers to the principle or relationship of cause and effect, while cause is just the agent that produces an effect

connection

Connection is vague and could mean any relationship; causality specifically means one thing directly causes another

relationship

Relationship is too broad; causality specifies a directional influence where one event produces another

Usage tip

Critical in research and data analysis to distinguish from mere correlation. Use when discussing whether one thing actually causes another, not just relates to it.

Etymology

Latin causalis (relating to a cause) from causa (cause, reason)
