-on-
-on-: Fractions
-on- turns a number into a fraction.
How It Works
| Number | With -on- | Meaning |
|---|---|---|
| du | duono | a half |
| tri | triono | a third |
| kvar | kvarono | a quarter |
| dek | dekono | a tenth |
A triono is not a part of three. It is one of three equal parts of something else, and you name that whole with de: triono de la kuko. A fraction is a noun, so it takes the usual endings: du trionoj is two thirds.
In front of another word, the short form duon- is used: duonhoro means half an hour. The ending also works as -ona and -one for adjectives and adverbs.
