-avo (non-lemma form of verb-forming suffix)

1. used with a stem to form the first-person singular imperfect of regular -are verbs

• ova

From earlier *-ado, from Proto-Finnic *-o (whence also Finnish -o) plus the inflectional stem of verbs ending in *-at'ak. Cognates include Finnish -uu.

-avo (front vowel harmony variant -ävö)

1. Forms abstract nouns from verbs in -ata.

-avo m (plural -avos)

1. forms fractionals

   ‎doze (“twelve”) + ‎-avo → ‎dozeavo (“one twelfth”)

-avo (feminine -ava, masculine plural -avos, feminine plural -avas) (adjective)
-avo m (plural -avos) (noun)

1. added to a cardinal number to signify one portion of a whole divided into that number of pieces. Creates both nouns and adjectives.

Ex. "Un doceavo del bizcocho" ("One twelfth of the cake")

Only used for numbers greater than 10. Less common for numbers 1000 and above (use the vigésimo ordinal form which is also signifies portions). If the cardinal number ends in -a, do not add another one (cuarentavo instead of !cuarentaavo). The conversion of cien is irregular (centavo)
