Learn Hardcore Esperanto: La infano ludas bone.

La is the definite article in Esperanto, equivalent to the in English. It signals that the noun following it, infano, is definite or specific.

What is the meaning of infano and how do you know it’s singular?

Infano means child. In Esperanto, nouns end with -o in the singular. To form the plural, you would add -j (yielding infanoj for “children”). Since there is no -j here, it is singular.

How is the verb ludas constructed and what does it indicate?

Ludas comes from the verb ludi, meaning to play. The ending -as marks the present tense in Esperanto, so ludas translates as plays.

Why does the word bone end in -e and what role does it serve?

In Esperanto, adjectives take the ending -a (for example, bona means “good”), while adverbs, which modify verbs, take the ending -e. Therefore, bone is the adverbial form of bona and means well, explaining how the child plays.

Why is bone positioned at the end of the sentence?

While Esperanto’s word order is flexible due to its clear grammatical markers, the most natural—and common—placement for an adverb like bone is immediately after the verb it modifies. In La infano ludas bone, placing bone after ludas clearly specifies the manner in which the child plays.

How can a learner quickly identify the roles of words like infano, ludas, and bone in an Esperanto sentence?

Esperanto’s consistent use of word endings makes it easier to identify each word’s role. Nouns end in -o (infano), verbs in the present tense end in -as (ludas), adjectives in -a, and adverbs in -e (bone). This regularity helps learners immediately recognize that infano is a noun (child), ludas is the present tense verb (plays), and bone is an adverb (well).
