The Northwest Caucasian languages are extremely odd. There are not many of them, and we already went over one of the strangest one of them all, Ubykh. Now we will look at them in general and also look at Abaza and Abkhaz.

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.
All NW Caucasian languages are characterized by a very small number of vowels (usually only two or three) combined with a vast consonant inventory, the largest consonant inventories on Earth. Almost any consonant can be plain, labialized or palatalized. This is apparently the result of an historical process whereby many vowels were lost and their various features became assigned to consonants. For instance, palatalized consonants may have come from Ci sequences and labialized consonants may have come from Cu sequences.
The grammars of these languages are complex. Unlike the NE Caucasian languages, they have simple noun systems, usually with only a handful of cases.
However, they have some of the complex verbal systems on Earth. These are some of the most synthetic languages in the Old World. Often the entire syntax of the sentence is contained within the verb. All verbs are marked with ergative, absolutive and direct object morphemes in addition to various applicative affixes. These are akin to what some might call “verbal case.” For instance, in applicative voice systems, applicatives may take forms such as comitative, locative, instrumental, benefactive and malefactive. These roles are similar to the case system in nouns – even the names are the same. So you can see why some call this “verbal case.”
NW Caucasian verbs can be marked for aspect (whether something is momentous, continuous or habitual), mood (if something is certain, likely, desired, potential, or unreal). Other affixes can shape the verb in an adverbial sense, to express pity, excess or emphasis.
Like NE Caucasian, they are also ergative.
NW Caucasian makes it onto a lot of craziest language lists.
These are some of the strangest sounding languages on Earth. Of all of these languages, Abaza has the most consonants. Here is a video in the Abaza language.
Abkhaz is an extremely difficult language to learn. Each basic consonant has eight different positions of articulation in the mouth. Imagine how difficult that would be for an Abkhaz child with a speech impediment. Abkhaz seems to put agreement markers on just about everything in the language. Abkhaz makes it onto many craziest language lists, and it recently got a very high score on a weirdest language study.
Abkhaz is rated 6, hardest of all.
