I’ve recently been reading about Esperanto. It appears that a US Esperanto organization is just a few miles from where I live.
I took a look at the language, and it looks very easy to learn. It might be possible to have a conversation with very little work beyond memorizing vocabulary. One study showed that 150 hours of studying Esperanto can bring a native French speaker up to the level that it would take 2000 hours to reach in German.
Check out some of these studies on language acquisition:
Various educators have estimated that Esperanto can be learned in anywhere from one quarter to one twentieth the amount of time required for other languages...The Institute of Cybernetic Pedagogy at Paderborn (Germany) has compared the length of study time it takes Francophone high school students to obtain comparable ‘standard’ levels in Esperanto, English, German, and Italian. The results were:
• 2000 hours studying German = 1500 hours studying English = 1000 hours studying Italian = 150 hours studying Esperanto.…In one study, a group of European secondary school students studied Esperanto for one year, then French for three years, and ended up with a significantly better command of French than a control group, who studied French for all four years.
The grammar is very regular–just take a simple root word and modify it:
- Nouns
- all nouns end in -o
- to make them for a change the suffix to -oj
- to mark the object of a sentence add -n
- Adjectives
- all adjectives end in -a
- Verbs
- all verb infinitives end with -i
- present tense: -as
- past tense: -is
- future tense: -os
- no other verb conjugations
- Adverbs: take an adjective and add -e
- to make a noun diminutives add -et- between the root and the suffix
- to reverse a word's meaning, prefix with mal-
Here is a basic introduction to the language:
