Is Esperanto hard to learn for English speakers?

Esperanto is not hard for an English speaker; it was designed not to be, and the design works. Its whole grammar was published as sixteen short rules, its verbs have no irregular forms, and every word is read exactly as it is written. But a short rulebook is not the same as a short road. The rules leave several things to be learned by use, and four of them catch English speakers in particular: the object ending -n, a table of forty-five small words, verbs that cannot take an object, and knowing which of the words you can build people actually say.

What the sixteen rules make easy

In 1905 Zamenhof published the Fundamento de Esperanto, as a definitive guide to the language, and its grammar section is sixteen numbered rules. Three of them remove most of what makes other European languages slow:

Verbs. "The verb does not change its form for numbers or persons," says rule 6: mi faras (I do), la patro faras (the father does), ili faras (they do). Each tense or mood is one ending, the same on every verb in the language:

That table is the whole verb system an English speaker needs for everyday speech. There is no list of irregular verbs to learn, because there are none — compare the six verbs that carry a large share of everyday Spanish.

Spelling and stress. "Every word is to be read exactly as written, there are no silent letters" (rule 9), and the stress always falls on the second-to-last syllable (rule 10): hos-pi-TA-lo. Once you know the alphabet, you can read any Esperanto word aloud. The one trap is that some letters do not mean what they mean in English: c is the ts of "wits", j is the y of "yoke", and ĝ is the j of "join".

One article. There is no word for "a", and the word for "the", la, is the same "for all genders, numbers, and cases" (rule 1). Nothing like German's six spellings of "the".

Where the rules run out

The sixteen rules are short. The standard reference grammar, Bertilo Wennergren's Plena Manlibro de Esperanta Gramatiko (PMEG), is a whole book, because each rule turns out to have uses the rule does not spell out. These are the four that cost English speakers the most time.

1. The -n ending

Rule 2 says the object of a sentence "adds an n". English shows the object by word order alone, so the -n is easy for an English speaker to leave off. It matters because Esperanto's word order is free, and the -n is what tells you who did what:

• La hundo ĉasis la katon. — The dog chased the cat.
• La katon ĉasis la hundo. — Also "the dog chased the cat".

An adjective agrees with its noun, so the -n has to go on both: Mi havas bonan amikon (I have a good friend), and in the plural, bonajn amikojn.

Then the ending does three more jobs. It shows movement towards somewhere (rule 13): Kien vi iras? — "Where are you going (to)?" PMEG's example, from the Fundamento's own exercises, shows the difference one letter makes:

• La birdo flugas en la ĉambro. — The bird is flying about in the room.
• La birdo flugas en la ĉambron. — The bird flies into the room.

It also marks a point in time — Merkredon mi kantos, "On Wednesday I will sing" — and a length or amount: Mi veturis du tagojn, "I travelled for two days". None of these is hard to understand. All of them are easy to forget while speaking.

2. Forty-five correlatives

PMEG counts 45 tabelvortoj, "table words": the small words for who, what, where, when, why, how and their answers. They are perfectly regular — five beginnings times nine endings — which is exactly what makes them hard to keep apart at speed. Here are four of the nine rows:

The other five rows end in -a (kind), -al (reason), -el (manner), -om (amount) and -es (whose). In a table they look trivial. In conversation, kiu, kio, kia and kie differ by a single vowel, and none of them looks like its English equivalent, so they are learned by drilling, not by working out.

3. -igi and -iĝi: verbs that do, and verbs that happen

English lets one verb do two jobs: "I opened the door" and "the door opened". Esperanto does not. A verb either takes an object or it does not, and the suffix -iĝ- turns the first kind into the second:

• La knabo malfermis la pordon. — The boy opened the door.
• La pordo malfermiĝis. — The door opened.

The classic case is begin and end. PMEG's advice is blunt: do not say Kiam komencos la koncerto?, because a listener will want to know what the concert is going to begin. Say Kiam komenciĝos la koncerto? — "When does the concert begin?" — and La leciono finiĝis, "the lesson ended". The opposite suffix, -ig-, makes a verb that causes something: manĝi is to eat, manĝigi to feed.

4. Building words, and knowing which ones people say

Esperanto's affixes let you build words you were never taught. Mal- gives the direct opposite: bona → malbona (good, bad), granda → malgranda (big, small), amiko → malamiko (friend, enemy). It is the feature Esperanto is famous for. What is said less often is that the freedom has limits in both directions.

Overuse. PMEG notes that mal- works only for words that have a direct opposite, and that it is not the same as ne (not). Neutila is "not useful"; malutila is "harmful". Choosing the wrong one says something you did not mean.

Underuse. A word that can be built is not always the word people use. Malsanulejo — mal-san-ul-ej-o, "place for sick people" — is a correct word for a hospital, and in our frequency-ordered list it comes far later than hospitalo, the international word, which is much more common. Only reading and listening tell you which of two correct words is the usual one.

Typing six letters with hats

Esperanto has six letters of its own: ĉ, ĝ, ĥ, ĵ, ŝ and ŭ. They are not on most keyboards. The Fundamento itself allows writing h in place of the circumflex and leaving the mark off ŭ, so ŝanĝi (to change) becomes shanghi; in typing, many people use x instead, sxangxi, because x is not an Esperanto letter and software can turn it back automatically. It is a nuisance for a week, not a difficulty — but install a keyboard layout early, because a letter without its hat can be a different word: ŝi is "she", si is "himself" or "herself".

The words: a head start, if you speak a European language

About 80% of Esperanto's vocabulary comes from the Romance languages, the rest mainly from Germanic, Greek and Slavic. English took so much from Latin and French that an English reader recognises many roots on sight: lingvo (language), hospitalo, koncerto. Not all of them, though — hundo is a dog, knabo a boy and ŝati to like — and for a speaker of Chinese, Japanese or Arabic, much less of it is familiar. "Easy vocabulary" is a European head start, not a universal one.

The endings, at least, do not add to the memorising. In Esperanto film and television subtitles we counted 36,346 different word forms; strip the regular grammatical endings and only 20,811 stems remain. Reaching 95% of what is said takes 16,359 forms but only 6,423 stems. That measurement, and why it is not a fair ranking against other languages, is in how many words you need to speak Esperanto.

Few native speakers, and no one to copy

The genuinely hard part of Esperanto is not on the page. Ethnologue gives about 1,000 first-language speakers, and estimates of everyone else who speaks it range from tens of thousands to around two million. No country has adopted it officially, so there is nowhere to move to where it is the everyday language: immersion means seeking out meetings, online groups and recordings.

There is also no native-speaker yardstick. Native speakers, Wikipedia notes, "do not occupy an authoritative position in the Esperanto community". Good usage is described instead from the Fundamento, from Zamenhof's own writing and from the best later authors; PMEG illustrates its rules with quotations, many of them Zamenhof's, which is why the examples above come from it. For a learner, that means good models have to be sought out rather than absorbed.

So is Esperanto hard?

• Verbs, spelling and pronunciation: easy — one ending per tense, no irregular verbs, no silent letters and fixed stress.
• Vocabulary: easy for an English speaker, thanks to Romance roots, though not every root is guessable; much harder from outside Europe.
• Grammar: easy to learn, slower to use — the -n ending, the correlatives and -iĝi are where English habits cause mistakes.
• Immersion: the real difficulty — a small, scattered community with few native speakers.

It sits at the easy end of the scale, which is the subject of the easiest languages to learn for English speakers; the other end is in the hardest languages to learn. What all this means in weeks and months is in how long it takes to learn Esperanto.

The most common Esperanto words are free and in frequency order, and the two-minute Esperanto vocabulary test estimates how many you already know. The Esperanto course — Verbavia (our own course), free in any browser — is hand-written from the first lesson to C2.
