Forms

immēnsitās f (genitive immēnsitātis); third declension[1] Also spelled ⟨inmēnsitās⟩.[2][3]

Etymology

It is from Latin immēnsus (“immeasurable, boundless”) + -tās.[2][1][4]

Earliest recorded meaning

Cicero is its first author, in the De natura deorum: in hāc immēnsitāte lātitūdinum, longitūdinum, altitūdinum īnfīnīta vīs innumerābilium volitat atomōrum, “in this immensity of breadths, lengths and heights flies an infinite number of countless atoms”.[2][4][3][5]

Semantic evolution

Cicero also has the plural, the heights of mountains and immēnsitātēs campōrum, vast plains.[2][3] The TLL counts two uses in Cicero and one in Apuleius, then the Edict of Diocletian, Ammianus and the Church writers;[4] Apuleius says that the whole immensity of the earth is enclosed by the Atlantic sea.[2] Augustine speaks of the immensity of the ocean,[4] and Christian writers used it above all of God and his works, of their greatness as much as their extent.[4][6]

In Medieval Latin it was hugeness, abundance and eternity:[7] it was used of space, of time, of number and of degree,[8] and Albertus Magnus writes of the whole immensity of time, which some called eternity.[8] Anselm uses it of the infinity of God the creator;[9] it also meant a great amount, the great size of a giant, and in a letter of 1337 a title of honour.[9]
