The Origin of Imbalanced or Unbalanced

Both words come from the noun balance.

The word balance entered English through Old French and ultimately comes from the Latin word bilanx, meaning “having two scales.”

Imbalanced

The prefix im- means “not.” Therefore, imbalanced literally means “not balanced.” It became common in scientific, medical, economic, and technical writing.

Unbalanced

The prefix un- also means “not.” However, unbalanced developed a broader everyday meaning. It is often used for physical instability, emotional instability, and uneven structures.

Because both prefixes mean “not,” the meanings overlap in some situations. That overlap is why writers often confuse them.
