Naiad
noun /ˈnaɪ.æd/ — A water nymph; the spirit inhabiting a freshwater source
Definition
In Greek mythology, a type of nymph who presides over a body of fresh water — a spring, stream, brook, river, or lake. Each freshwater source had its own naiad, tied to the health and life of that specific water.
Beyond the definition
The personality of water. A naiad makes the claim that every spring has its own character, that each stream is singular — that the world's water is not generic but specific, personal, inhabited.
Origin & history
From Greek 'Naïas' — from 'naein' (to flow). The flowing ones. Related to 'natare' (to swim) and ultimately to the Proto-Indo-European root for water and swimming, shared with 'navy' and 'navigate'.
