Lesson One - Leciono Unu

Free Correspondence Course - Senkosta Kuresponda Kurso

The Free Esperanto Course begins simply, but by Lesson 10 you will understand sophisticaed Esperanto with complex syntax.  Upon satisfactory completion of the series of ten lessons, you will receive a framable "Certificate of Completion".

Let's get started!

Language is all about things (nouns) and their actions (verbs) of energetic thing:

One thing…Acts on…Another thing
a bird…catches…an insect
subject nounverbobject noun

Esperanto is “grammar-coded” - you can tell what part each word plays in a sentence from the word endings:

single subject nounsingle object noun
plural subject nounplural object noun

To show when the action takes place, the verb tense (time) is changed by putting these endings on the verb roots:

past tense-isshows an action completed
present tense-asdescribes it as it happens
future tense-osaction still to begin



Every noun and every verb follows the above rules without exception.

In Esperanto, things have no gender (they are not male or female, as in many other languages). There is only one word for “The”, no matter if the noun is singular or plural, object or subject. Therefore:

La birdoj kaptas la insektojn.
La birdo kaptis la insekton.

In Esperanto the word order matters less than in English. All the following sentences describe the same action (only the emphasis is changed):

Viro legas libron.Viro libron legas.Libron legas viro.
Libron viro legas.Legas viro libron.Legas libron viro.
 A man reads a book. 

Here are some words in Esperanto (the apostrophe indicates an incomplete word, a root):

NounsVerbs (roots)More nouns
amiko(friend)far’(do, make)kafo(coffee)

Each Esperanto letter has only one sound, always. Here is a guide to some of the sounds. The stress is always on the next-to-last syllable of a word.


c=ts (in lots); oj = oy (in boy); G = g (in go)
kn are always pronounced separately: k-nabo
