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 Anyin language in terms of how difficult it would be for an English speaker to learn it.
Anyin is a language spoken by 860,000 people in Côte d’Ivoire and Ghana. It is relatively straightforward as far as African languages go. Probably the hardest part about the language is that it is tonal, and it does have two tones. The phonology does have the unusual +-ATR contrast which will seem very odd. ATR stands for advanced tongue root, so the language has a contrast between vowels with an advanced tongue root and without one. However, the grammar is pretty regular. There are few confusing phonological processes.
Anyi has a simple tense system, with only present, past and future. There is no aspect, mood or voice marking, and it lacks the noun class systems so common in many African languages. It has a plural marker, but it is often optional.
The syntax does have serial verbs, which will seem odd to Westerners. It distinguishes between relative clauses marked with bɔ and subordinate clauses marked with kɛ.
Anyin gets a 4 rating, very hard to learn.
