Esperanto/Introducing yourself

Be sure to make use of the pronunciation appendix.

Grammar
Since Esperanto is a very regular language, all its rules can be applied universally without exceptions. This means Esperanto grammar concepts are much easier to understand than those of natural languages. In this first lesson, we shall examine how to form nouns, adjectives, and the present tense.

Nouns
In any language, nouns are words that designate a person, place, thing, idea, or quality. Some examples of nouns in English are: "house", "friends", "cake", "John", "France", and "gardens".

In Esperanto, all nouns end in -o. The part of the word that goes before the -o is known as the root. For example, in the word urbo (city), urb- is the root and the -o makes it a noun.

To make a noun plural, add a -j to the end, for example urboj (cities).

Some examples of nouns in Esperanto: (human),  (house),  (friends),  (cake),  (John),  (France) and  (gardens).

To say a or an, as in "a town", just say the noun on its own, e.g. urbo (town, a town). There is no indefinite article ("a" or "an") in Esperanto.

The word for the is la, e.g. la urbo (the city). La never changes for singular or plural.

Adjectives
Adjectives are words that describe a noun. Some English examples are: "happy", "tired", "beautiful", "young" and "fresh".

To change an Esperanto noun into its corresponding adjective, replace the -o with an -a. For example, urbo (town) gives rise to urba (urban, "relating to a town").

Some examples of adjectives in Esperanto: (happy),  (tired),  (beautiful),  (young) and  (fresh).

In Esperanto, an adjective must "agree in number" with the noun it describes. This means that if the noun is singular, the adjective must also be. If the noun is plural, the adjective must also be, too. Some examples: la freŝa kuko (the fresh cake), la freŝaj kukoj (the fresh cakes); feliĉa homo (a happy person), feliĉaj homoj (happy people).

The prefix mal- changes an Esperanto word into its opposite meaning – a feature that greatly reduces the vocabulary. Here are some examples of mal- words in Esperanto: (unhappy),  (alert, not tired),  (ugly),  (old) and  (stale).

Adverbs
Adverbs are words that describe a verb, an adjective, or another adverb. They indicate manner, place, time or quantity. Some English examples are: "quickly", "orally", "at home", and "in writing".

To change an Esperanto word into an adverb, replace the usual ending (-a for adjectives, -o for nouns, and -i for verbs) with -e. The meaning of the base word determines whether it becomes a manner, place, time or quantity adverb.
 * Manner – How something is done, "He runs quickly." ; "He submitted it in writing."
 * Place – Where something is done, "He runs at home."
 * Time – When something is done, "He runs on Sunday."
 * Quantity – "He runs a lot."

Some examples of adverbs in Esperanto: (quickly),  (orally),  (at home), and  (in writing).

Please note that not all adverbs use this rule, but the overwhelming majority of them do. Once you are introduced to these adverbs, it will be obvious why there are exceptions.

Personal pronouns
In Esperanto there are ten personal pronouns. However, you will initially need to only know seven of these pronouns.


 * The other pronouns ("", "") will be covered later.
 * "Ci" is rarely used, and isn’t recommended.
 * The third person neuter singular pronoun, "ĝi", is not exactly the same as the English "it" because it can be used as a gender-neutral pronoun for a living person. For example, "Look at that baby. I can't tell if it is a boy or a girl."
 * There also are some neologism gender-neutral pronouns. Although none of them are sanctioned by the Akademio de Esperanto, they are still commonly used in online spaces, which is why they are mentioned here. "Ri" is the most popular.

Possessive pronouns
To turn a personal pronoun into a possessive pronoun (which is an adjective), simply add an -a to the end.

Verbs – present tense
The basic form of a verb is called its infinitive. In English, this is the part of the verb that has "to" in front of it, as in the sentence "John likes to play football". In Esperanto, the infinitive simply has an -i after the root, e.g. (a game),  (to play).

The present tense has three forms in English. For example, one can say either "I kick", "I am kicking" or "I do kick"; "he laughs", "he is laughing", "he does laugh"; "Robert eats the cake", "Robert is eating the cake", "Robert does eat cake". All these forms are represented under one form in Esperanto.

To form the present tense of any Esperanto verb, simply substitute the -i in the root with -as. Some examples: mi legas (I am reading), li ridas (He is laughing), Roberto manĝas la kukon (Robert eats the cake).

You will also note that there is no verb conjugation in Esperanto for person. For example, in English you would say "Bob eats", "I eat", and "She eats"; In Esperanto, you would use the same form of the verb: "Bob manĝas", "Mi manĝas", "Ŝi manĝas".

Objects and the accusative case
Like in English, every complete declarative sentence in Esperanto requires at least two parts: a subject and a verb. In the sentence "I ate", the subject is "I" and the verb is "ate". A subject is a noun which performs an action. However, in the sentence "I ate spaghetti", there is a third word: "spaghetti". The word "spaghetti" in this sentence is what is known as a direct object. A direct object is a noun which is having an action performed on it. It is being "verb'ed", so to speak.

Take special note of the last sentence. In the first three sentences, the direct object directly followed the verb. However, in the last sentence, the word "Jane" directly follows the verb "gave". So why isn't Jane the direct object of the sentence? Because Jane is not having an action performed on her by the verb of the sentence, "give". Frank is not giving Jane, Frank is giving flowers to Jane. Since the flowers are what is being given, the flowers are the direct object.

So what is Jane in this sentence, then? Jane is what is known as an indirect object. An indirect object is a noun which is neither performing an action nor having an action performed directly upon it, but receiving the action of the verb less directly than the direct object (hence the name). In Esperanto, the indirect object will always take a preposition. For example, "Frank baked Jane a cake" becomes "Frank baked a cake for Jane."

This basal reader stuff is real cute. But the simplicity quickly falls apart with more complex statements. Let's try some more advanced sentences in English.

As you can see, English sometimes chokes on the complexities of real life. The incorrect understanding of the sentence about the First Amendment has the same basic structure as "The pilot makes the heading in the flight plan to the north.", giving the false parse a similar structure to "The amendment redirects the trust in their ability to criticize, into the Constitution.", which would mean "The First Amendment has persuaded the citizenry to trust that they are able to criticize the governor's administration of the presumptive draft on the grounds that the governor is administrating the presumptive draft unconstitutionally instead of trusting that they are able to criticize the governor's administration of the presumptive draft on other grounds.", which, depending on the minute details of history, the English language, and then-current law, could actually make sense, but is not the correct understanding of the grammar or the meaning of the sentence. English speakers can use their intuition to get past part of this problem, but in controversies, debates, and trials where words are deliberately or accidentally twisted, in technical fields, in natural language processing, and with English as a Foreign Language, it becomes increasingly difficult. Now you know one of the many reasons why natural language processing is an unsolved problem in computer programming. Another reason is that most English words have multiple meanings, up to 60 or even 100 meanings. Most Esperanto words only have one meaning, and its words with more than one meaning usually only have 2 or 3 meanings. Google Translate makes countless errors, and as such is no substitute for taking the courses over there at Lernu.

We'll try that again by shoehorning it into Esperanto. These sentences are kind of stilted, and in another situation one would use a very different wording. The stilted wording more or less preserves the basic structure of the English sentences, though. We'll start with the translation of "Now let's try more advanced sentences in Esperanto.", which is "Nun ni provu iom Esperantajn frazojn kiuj estas pli progresintaj."

In English, word order in a sentence helps determine whether a noun is a subject, a direct object, or an indirect object. In English, the order is often "subject, verb, direct object", "direct object, subject, verb" or "subject, verb, indirect object, direct object", and various other orders. As you can see from the table above, there are many plausible but incorrect comprehensions of the English sentences, but no plausible incorrect comprehensions of their Esperanto translations. That's because grammar in planned languages, such as Esperanto, tends to be much more precise than in natural languages. Esperanto uses affixes to explicitly and unambiguously mark words for part of speech, case, gender and number. Thus, part of speech tagging of Esperanto's single-stem words is already solved. In order to make a direct object in Esperanto, one simply adds the letter "n" to the noun (if the noun is plural, the "n" is added after the "j").

Therefore, in Esperanto, subjects, verbs, and direct objects can be put in any order, with little, if any, loss of clarity. All of the following sentences, which mean "the apple loves the banana" are grammatically correct in Esperanto.
 * La pomo amas la bananon.
 * La pomo la bananon amas.
 * Amas la pomo la bananon.
 * Amas la bananon la pomo.
 * La bananon la pomo amas.
 * La bananon amas la pomo.
