List of Languages Showing Learning Difficulty

Based on empirical research. Including number of memorization units.

RESULTS OF RESEARCH
     The results of research into the suitability and difficulty of languages were astounding.  It should be noted that one language scored so much above all of the others that it stood out scientifically and empirically as the easiest and best.
 
     No other language, not even English, is even close to the easiest language.  The questions used in the study provide an empirically verifiable level of difficulty showing how difficult a language is to learn.  The language easiest to learn and use was basic Esperanto (A SCIENTIFICALLY DEVELOPED VOCABULARY OF HIGHEST UTILITY WORDS using international words, 70 percent English) which tested out at only 1224 memorization units.  The full International Language (also known as Esperanto) tested out at 12,000 memorization units for average adult understanding.  The next closest candidates were Malay with 40,000;  Burmese with 64,000;  and English with 122,520.  The Average difficulty of languages evaluated was 201,000 memorization units.  That means that the average language was about 200 times as difficult as the easiest.  The most difficult languages had over 1000 times more memorizations than the most efficient.  The figure in the middle is the number of memorization units needed for 90-100 percent understanding

Languages not shown had a suitability score of four or less or information was unavailable. 
      Fluency in English requires nearly ten times the memorization facts required for Esperanto.  This makes Esperanto from 3.3 to 300 times easier to learn than other languages and 10 times easier to learn than English.  For English speakers it is even easier because 60-70 percent of Esperanto vocabulary is similar to an English word with a similar meaning.  How does this compare with other researchers?  Per Thorndike, Esperanto is four times easier.  Per Sherwood, five to ten times easier.  Per The California Esperanto Education Commission, five times easier.  Per The World Almanac, five to twenty times easier.  Per Janton, eight times easier than French.
