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 Tsez language in terms of how difficult it would be for an English speaker to learn it.
NE Caucasian languages have the uvulars and ejectives of Georgian in addition to pharyngeals, lateral fricatives, and other strangeness. They have noun classes like the Bantu languages (but usually fewer). Nevertheless, they have noun class agreement markers on verbs and adjectives. One thing NE Caucasian has is a lot of case. Some languages have 40+ cases. The cases are built from the ground up via two forms – one a spatial form such as in, on or around and the other a directional motion form such as to, from, through or at.
Tsez has 64-126 different cases, making it by far the most complex case system on Earth! It is one of the few languages on Earth that has two genitive cases – Genitive 1 (-s) and Genitive 2 (-z). Genitive 1 is used when the genitive’s head noun is in absolutive case, and Genitive 2 is used when the genitive’s head noun is in any other case. It also has four noun classes. It is said that even native speakers have a hard time picking up the correct inflection to use sometimes.
In Tsez, you need to know a lot Tsez grammar to communicate at a basic level. Look at the sentence:
English: “I like your mother.”
Tsez: Дāьр деби энийу йетих. (Dǟr debi eniyu yetix.)
In order to speak that sentence in Tsez, you need to know:
• the words themselves (word order is not as important)
• that the verb -eti- requires the subject to be in the dative/lative case and the object to be in the absolutive
• the noun class for eniyu (class II)
• the dative/lative form of di “I”, which is dǟr
• the genitive 1 form of mi “you”, which is debi
• the congruence prefix y- that corresponds to the noun class of the absolutive argument of the phrase, in this case “mother”
• the present tense ending for vowel-final verbs -x
Tsez is rated 6, hardest of all.
