Forms

extēnsiō f (genitive extēnsiōnis); third declension[1]

Etymology

It is from extendō “to stretch out” with the suffix -tiō.[2][1][3] It is also written ⟨extentiō⟩.[4][5]

Earliest recorded meaning

Köbler's first source is Ambrose, whom he dates c. 340–397 AD.[6]

Semantic evolution

It meant stretching out, extension, the span covered by stretching, as of strings in Isidore and of limbs in Caelius Aurelianus.[2][7][4] In Vegetius it meant a swelling.[4]

In Ecclesiastical Latin it meant extension, addition.[8] Medieval Latin used it for spreading, expanse, and the surveying of land.[9] British Medieval Latin used it for stretching taut and, in medicine, swelling.[10] It survives in Italian estensione and French extension, and English extension came about 1400, “a swelling”.[1][3]
