-os m (feminine singular-oasã,masculine plural-osh,feminine plural-oasior-oase) or (feminine-ose ,feminine plural-osi)

1. -ous; used to form adjectives

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)

-os

1. will;ending of future tense in verbs.

   Mi iros al la vendejo. ―Iwill go to the store.

FromProto-Finnic*-os. Equivalent to-o +‎-s, or re-extracted from verbs with stems ending ino.

• IPA^(key): /-os/,[-o̞s̠]

-os (front vowel harmony variant-ös,linguistic notation-Os)

1. Forms nouns denoting the result of the action of a verb.

   ‎liittää(“to join”) + ‎-os → ‎liitos(“joining, joint”)

   ‎muuntaa(“to change, convert”) + ‎-os → ‎muunnos(“conversion”)

Roots with the neutral front vowels-e-,-i- take the back-vocalic allomorph-os (e.g.pettää(“to deceive, to betray”) →petos(“betrayal, fraud”),piirtää(“to draw”) →piirros(“drawing”)). The form-ös is only used when the first syllable of the root contains what is considered a front vowel under harmony, i.e.-ä-,-ö- or-y- (e.g.kääntää(“to turn; to translate”) →käännös(“turn; translation”),kytkeä(“to connect”) →kytkös(“connection”),näyttää(“to show”) →näytös(“act”)).
