Learn Hardcore Esperanto: Morgaŭ vi devos helpi la infanojn, kaj ili povos ludi en la parko. - Tomorrow you must help the children, and they can play in the park.

Devos comes from the verb devi, meaning "must" or "have to". In this sentence, it is conjugated in the future tense (with the ending -os), so it translates to "will have to"—indicating that the obligation to help will occur tomorrow.

What does povos mean, and how is it formed?

Povos is derived from the verb povi, which means "to be able" or "can". It is also in the future tense (using -os), so it translates to "will be able"—showing that the children will have the ability to play in the park in the future.

Why is helpi in its infinitive form instead of being conjugated like the modal verbs?

In Esperanto, when a modal verb such as devos (from devi) is used, it is followed by another verb in its infinitive form. Here, helpi (meaning "to help") remains in the infinitive because the modal verb carries the tense and mood, much like in English when we say "will have to help".

Why is infanojn written with an -n at the end?

The -n ending in infanojn marks the accusative case in Esperanto. This indicates that infanojn (children) is the direct object of the verb helpi. The accusative is consistently used to show the target of an action.

What role does morgaŭ play in the sentence, and why is it placed at the beginning?

Morgaŭ means "tomorrow". It functions as a time expression, providing important context about when the actions will take place. Placing it at the beginning is common in both Esperanto and English to set the temporal framework of the sentence.

How is the compound sentence structured in this example?

The sentence is divided into two independent clauses connected by "kaj" (which means "and"). The first clause, "Morgaŭ vi devos helpi la infanojn", states the obligation you will have tomorrow, while the second clause, "ili povos ludi en la parko", explains that the children will have the ability to play in the park. The comma before "kaj" helps to clearly separate these two ideas.

How are modal verbs like devi and povi conjugated in Esperanto?

Esperanto verbs are highly regular. For modal verbs: • With devi, you add -os to the stem dev- to form devos (meaning "will have to"). • With povi, you similarly add -os to the stem pov- to form povos (meaning "will be able"). This regular conjugation applies to all verbs in Esperanto, making the language predictable and easier to learn.

What is the function of en la parko in the sentence?

En la parko is a prepositional phrase meaning "in the park". The preposition en indicates location, while la parko specifies the particular place. This phrase tells us where the children have the opportunity to play, completing the picture of the future scenario.
