The word level originates from Latin and Old French roots meaning “flat,” “even,” or “uniform.” Etymologically, level refers to something that is horizontal, equal, or unvaried in height, degree, or condition—implying balance, smoothness, or equal distribution.
Etymological Breakdown:
1. Old French: level or livelle
- Meaning: “even,” “flat,” “level”
- Borrowed from Latin libella, meaning “a small balance” or “spirit level”
- Libella itself was a diminutive of libra, meaning “balance” or “scale,” as used in the context of measuring or finding horizontal alignment
2. Latin: libella
- Meaning: “small balance,” “a level,” “spirit level” (an instrument used to determine if a surface is horizontal)
- From libra = “a scale,” “a balance” (referring to the weighing balance with two equal pans)
- PIE root: leip- = “to remain, to be level”
- In its original use, a libella was an instrument used to ensure that surfaces were even or horizontal, and from this evolved the idea of being in alignment or uniform.
3. Middle English: level (14th century)
- Borrowed from Old French level and livelle
- Initially referred to an instrument for measuring evenness or levelness
- By the late Middle Ages, it was extended to describe the quality of being even or uniform in height, condition, or status
4. Modern English: level
- Meaning expanded to cover:
- Flatness or evenness in physical space (e.g., “level ground”)
- Equality or uniformity in status or degree (e.g., “level playing field”)
- Measurement of things being aligned or balanced (e.g., “level of development,” “level of skill”)

Level = “Flat or even”
