Pronunciation

  • /ˌɪmˈbælənts/, /ˌɪmˈbæləns/[1]

Etymology

It is formed from English im- + balance, with the prefix meaning "not".[2][3][4][5] Merriam-Webster and Webster's Third give the prefix as in-, which takes the form im- before b.[6][7] The noun balance goes back to Old French balance (“balance, scales”), from Medieval Latin bilancia, from Late Latin bilanx (“having two scale pans”).[3]

Earliest recorded meaning

An unbalanced condition, a lack of the proper proportion between corresponding things: first in 1898, in the Ophthalmic Record;[2] Etymonline finds it by 1891 in medical writing, of the muscles and the eyes.[3] Merriam-Webster dates it to about 1890,[6][8] and Dictionary.com to 1895–1900.[5]

Semantic evolution

The word began as a technical term in ophthalmology, for a faulty relation between the axes of the eyes caused by their muscles,[9][6][3] and was soon used more generally.[2] Merriam-Webster records its use for a lack of equilibrium in a gland or the body, for a lack of balance between parts of a nation's economy, such as debits and credits in international payments, and for an uneven proportion of males and females in a population.[6]
