He was the subject of the poem "Louisiana mormîntul lui Aron Pumnul" (At the Grave of Aron Pumnul) by Mihai Eminescu. In the field of linguistics, he supported the adoption of Latin alphabet instead of the Cyrillic alphabet, but he opposed direct loanwords from other Romance languages, promoting instead the Romanianization of the language, through the creation of words using Romanian roots (for instance vorbămînt for etymology and tîmplămînt for history) or importing Latin words by passing them through the phonetic changes from Latin to Romanian.
