Etymology: The word "lymph" carries a surprising piece of mythology in its roots. Ancient Greek "nymphē" meant "bride" but also "spring water," and that second sense is where the story begins. Water sources were thought to be inhabited by nymphs, so the Greek word came to name the water itself. Latin borrowed the idea as "lympha," meaning clear water, and the sense of purity stuck. The Latin form passed into French as "lymphe," and English took the word from there. Because English "lymph" and "nymph" both descend from the same Greek word, they are doublets: two forms of one ancestor that reached English by different routes. "Nymph" kept the sense of a maiden spirit of woods and streams, while "lymph" narrowed to a clear fluid. Its modern anatomical meaning grew out of that sense of clear liquid. The fluid that bathes the body's tissues was seen as a watery, colourless substance, so the old word for spring water was applied to it.

Synonyms: fluid, serum
