• -es

The Esperanto suffixes -as, -is, -os, -us are related, and appear to have been inspired by previous language projects:

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 -is is likely cognate with the Latin perfect, as in amavit "s/he had loved", and the corresponding past infinitive amavisse.

-is

1. ending of past tense in verbs, e.g. ami to love, ŝi amis she loved.

(This etymology is missing or incomplete. Please add to it, or discuss it at the Etymology scriptorium.) Compare -us and -s.

-is (genitive -ise, partitive -ist)

1. Derives nouns.

   ‎petma (“to con, to trick”) + ‎-is → ‎petis (“conman, trickster, cheat, fraud”)

   ‎näitama (“to show”) + ‎-is → ‎näidis (“sample, specimen”)

2. Derives forms of nouns used in compounds.

   ‎väli (“field, area”) + ‎-is → ‎välis- (“outside”)

   võidma ("to spread", "to anoint") → võidis- in võidisvaal ("sperm whale")
