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.

Lakota and other Siouan languages may well be as convoluted as Iroquoian. In Lakota, all adjectives are expressed as verbs. Something similar is seen in Nahuatl.
Ógle sápe kiŋ mak’ú.
The shirt it is black he gave it to me.
He gave me the black shirt.
In the above, it is black is a stative verb and serves as an adjective.
Ógle kiŋ sabyá mak’ú.
Shirt the blackly he gave it to me.
He gave me the black shirt. (Lit. He gave me the shirt blackly.)
Bkackly is an adverb serving as an adjective above.
Lakota gets a 5.5 rating, nearly hardest of all.
