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.

The African Bantu language Ga has a bad reputation for being a tough nut to crack. It is spoken in Ghana by about 600,000 people. It has two tones and engages in a strange behavior called tone terracing that is common to many West African languages. There is a phonemic distinction between three different types of vowel length. All vowels have 3 different lengths – short, long and extra long. It also has many sounds that are not in any Western languages.
Ga gets a 6 rating, hardest of all to learn.
