Pronunciation

Forms

flexibilitās f (genitive flexibilitātis); third declension[1]

Etymology

It is from Latin flexibilis (“flexible, pliant”) + -tās.[1][2][3]

Earliest recorded meaning

Solinus is its first author: he says that the bulls of India turn their horns about with whatever flexibility they wish.[2][4][5][6] Isidore of Seville later repeats the passage.[2]

Semantic evolution

Late writers used it of bodies and of the mind or nature.[2][7] Cassiodorus writes of athletes who wrestle with the suppleness of their oiled bodies;[2][5] Augustine asks where a certain fragility or flexibility in a nature comes from;[2][5] and Venantius Fortunatus says that Hilary gave a stiff tongue flexibility and ease of speech.[2]

Medieval writers kept the physical sense: Albertus Magnus explains that a leaden rule adapts to the shape of any stone by its flexibility,[8] and William of Malmesbury and Gerald of Wales use it of limbs.[9] It was used of the voice in singing,[8][9] and figuratively of changeableness, especially of the free will, which can turn to good or to evil;[8][9][10] the Hungarian and Polish sources also have the sense of fickleness and inconstancy.[11][10] English flexibility came from it in the 1610s, of physical things, perhaps through French.[12]
