Etymology
Origin of causality
Explanation
Causality is the connection between a cause and its result or consequence. It is sometimes hard to figure out the causality of a stomach ache — it could be due to something you ate, or just a result of stress. You'll often find the word causality in scholarly or academic writing. Medical researchers might talk about the causality of various diseases, and a sociologist might study the causality of a childhood in poverty on future trouble in school. This noun comes from the adjective causal, "acting as a cause," from a Latin root, causa, or "cause."
