- This play of vowels is not an original idea of Zamenhof's: -as, -is, -os are found for the three tenses of the infinitive in Faiguet's system of 1765; -a, -i, -o without a consonant are used like Z's -as, -is, -os by Rudelle (1858); Courtonne in 1885 had -am, -im, -om in the same values, and the similarity with Esperanto is here even more perfect than in the other projects, as -um corresponds to Z's -us. —An International Language (1928)
The vowel of -as is likely cognate with the Latin present, as in amat "s/he loves", and the corresponding present infinitive amare, permitting the natural (for an European) -ant ending. i could come from past tense in Latin "ami, amisti".
