From the same root
Forms
incomplētus (feminine incomplēta, neuter incomplētum); first/second-declension adjective[1]
Etymology
It is from Latin in-2 (“not”) + complētus (“filled, complete”).[1][2][3][4] Conte marks it as Late Latin; it is the source of Italian incompleto.[4]
Earliest recorded meaning
Its only ancient source is the astrological work of Firmicus Maternus, who speaks of plans left imperfect and incomplete.[5][2][6][7]
Semantic evolution
Medieval writers used it widely for what is unfinished, imperfect or defective.[8][9] A constitution of 1265 is concerned that a peace should not stay unfulfilled for want of means,[9] and in Hungary a document of 1272 fears that the canons' wandering will leave the divine offices incomplete.[10] In England it was said of a church not yet finished, of business still to be settled, and of a book that is only partial, such as an incomplete life of Saint Godric in a list of 1442.[11]
In scholastic philosophy it was the opposite of complētus and perfectus: Albertus Magnus calls the being of matter the most incomplete and imperfect, and reports that alchemists hold every metal but gold to be incomplete,[9] and Thomas Aquinas speaks of incomplete acts, causes, definitions and forms.[12] Alexander Neckam uses it of a thirst that cannot be satisfied.[11] English incomplete comes from it in the late 14th century.[13]
