Etymology

It is borrowed from French viable (“capable of life”) (1530s),[2][3][4] from vie, life, from Latin vīta (see vital), and -able.[2][3][5]

Earliest recorded meaning

Of a newborn infant, capable of living: 1823 in Etymonline;[3] 1828–32 in Webster's Dictionary, which Barnhart and the OED take as the first record.[2][6]

Semantic evolution

An 1827 article on infanticide adopted the word from French because English had nothing as expressive, the proposed rearable being too vague.[3] Other physical uses, of seeds or cells able to grow, are from 1885.[6] The figurative sense, able to exist independently, is first recorded in 1848,[2][6] and workable or practicable in 1955 in Barnhart,[2] the mid-19th century in Word Origins.[7] Viability is from the 19th century.[4]
