Questions & Answers about La instruistino klarigis la regulon simple, por ke ĉiu studento komprenu ĝin.

Why does instruistino have so many parts, and what do they mean?

Esperanto words are often built from clear pieces:

• instru- = teach
• -ist- = a person who does something as an occupation or regular activity
• -in- = female
• -o = noun ending

So:

• instruisto = teacher
• instruistino = female teacher

This kind of word-building is very common in Esperanto.

How is klarigis formed?

klarigis comes from klarigi, which means to make clear or to explain.

It breaks down like this:

• klar- = clear
• -ig- = make something become / cause to be
• -i = infinitive ending

So klarigi literally means to make clear.

Then -is marks the past tense:

• klarigas = explains
• klarigis = explained
• klarigos = will explain

Why does la regulon end in -n?

The -n shows the direct object.

In this sentence, the teacher explained the rule, so the rule is what received the action. That is why it is:

• la regulo = the rule
• la regulon = the rule, as a direct object

This accusative -n is one of the most important parts of Esperanto grammar.
