Etymology

uneven = un<not> + even<level>

  • un: A prefix of negation, from Old English "un-," meaning "not."
  • even: From Old English "efen," meaning "level, equal, or smooth."

Etymology Origin:
The word "uneven" combines the Old English negative prefix "un-" with "even," which originally described flatness or equality. Over time, "even" expanded to include fairness and balance, while "uneven" retained its literal sense of physical irregularity and metaphorical sense of imbalance or inconsistency. The pairing reflects a straightforward oppositional structure common in Germanic-derived English words.
