Results. A ratings system was designed in terms of how difficult it would be for an English-language speaker to learn the language. In the case of English, English was judged according to how hard it would be for a non-English speaker to learn the language. Speaking, reading and writing were all considered.
Ratings: Languages are rated 1-6, easiest to hardest. 1 = easiest, 2 = moderately easy to average, 3 = average to moderately difficult, 4 = very difficult, 5 = extremely difficult, 6 = most difficult of all. Ratings are impressionistic.
Time needed. Time needed for an English language speaker to learn the language “reasonably well”: Level 1 languages = 3 months-1 year. Level 2 languages = 6 months-1 year. Level 3 languages = 1-2 years. Level 4 languages = 2 years. Level 5 languages = 3-4 years, but some may take longer. Level 6 languages = more than 4 years.
This post will look at the Karok language in terms of how difficult it would be for an English speaker to learn it.
Karok is formally a language isolate, but some theories put into Hokan, although Hokan itself is not even a recognized grouping.
Karok spoken by a few dozen people in northern California. The last native speaker recently died, however, there are ~80 people who have varying levels of L2 fluency.
In Karok, you can use a suffix for different types of containment – fire, water or a solid.
“throw into a fire”
“throw into water”
“throw through a solid”
The suffixes are unrelated to the words for “fire”, “water” and “solid”.
Karok gets a 6 rating, hardest of all.
