The humanists also sought to purge written Latin of medieval developments in its orthography. They insisted, for example, that "ae" be written out in full wherever it occurred in classical Latin; medieval scribes often wrote "e" instead of "ae". They were much more zealous than medieval Latin writers in distinguishing "t" from "c": because the effects of palatalization made them homophones, medieval scribes often wrote, for example, "eciam" for "etiam". Their reforms even affected handwriting: humanists usually wrote Latin in a script derived from Carolingian minuscule, the ultimate ancestor of most contemporary lower-case typefaces, avoiding the black-letter scripts used in the Middle Ages. Erasmus even proposed that the then-traditional pronunciations of Latin be abolished in favour of his reconstructed version of classical Latin pronunciation.
