Counting Things
Put the number first, and make the noun plural when there is more than one.
How It Works
| Subject | Object |
|---|---|
| unu kato | unu katon |
| du katoj | du katojn |
| tri libroj | tri librojn |
The number never changes. Only the noun takes -j and -n, so du stays du in du katojn. The word unu follows the same rule: write unu katon, never unun katon.
The noun after a number above one is plural, even though the number already shows how many: tri katoj, not tri kato. Esperanto has no word for a or an, so unu is used when the count matters.
When you order drinks, the noun counts the servings, so du kafojn, bonvolu asks for two coffees.
Examples (5)
- Ewa havas unu hundon.
Ewa has one dog.
Unu goes with a singular noun that adds only -n.
- Mi havas du fratojn.
I have two brothers.
Du stays plain; the noun adds -jn.
- Jen sep pomoj.
Here are seven apples.
Sep needs the plural pomoj, and there is no -n after jen.
- Tomasz legas kvin librojn.
Tomasz reads five books.
The number stays kvin; the noun carries -jn.
- Du kafojn, bonvolu!
Two coffees, please!
The noun counts the cups, and -n marks what is ordered.
Common Mistakes
Keeping the noun singular after a number above one.
Mi havas tri hundo.Mi havas tri hundojn.After tri the noun must be plural, and as the object it also takes -n.
Adding -n to unu.
Mi havas unun katon.Mi havas unu katon.Unu never takes -n. Only the noun does.
