The word pure originates from Latin roots meaning “clean,” “unmixed,” or “undefiled.” Etymologically, pure refers to a state of being free from mixture, free from corruption or stain, and ultimately in a condition of original or untainted wholeness—whether in a physical, moral, spiritual, or conceptual sense.
Etymological Breakdown:
1. Latin: purus
- Meaning: “clean,” “clear,” “unmixed,” “undefiled,” “genuine”
- Used to describe:
- Clear water or air
- Chaste behavior
- Moral innocence
- Unadulterated substances
In Classical Latin, purus signified both physical cleanliness and moral uprightness, bridging material purity and ethical or spiritual integrity.
2. **Proto-Indo-European (PIE): *peuə- / peur-
- Meaning: “to cleanse,” “to purify,” “to sift”
- This root also leads to:
- Sanskrit: pūta = “purified,” “holy”
- Greek: pyros = “wheat” (that which is sifted)
- Latin: putare = “to prune,” “to clear,” “to reckon” (→ compute)
The PIE root carries the sense of separating what is clean from what is impure—a refining process foundational to the idea of purity.
