Finally, Karaim coexisted with Lithuanian, Polish, Ukrainian, and Russian as a minority language in the other areas to which it dispersed where Karaims lived and had to speak the dominant majority languages. Karaim speakers show a strong tendency towards code-copying (Csató 2001). Code-copying differs from code-switching in that speakers don’t just switch from one language to another, but actually transfer lexical items and grammatical features from one language to another in processes that may be only for single instances, or that may have much more lasting effects on language typology (Csató 2001). Extensive code-copying is indicative both of the ever-shrinking population of Karaim speakers (leading to an insufficient Karaim lexicon and a high frequency of borrowing from Russian, Polish, and Slavonic languages) and of the high level of language contact in the regions where Karaim is spoken. Due to the very small number of speakers of Karaim and the high level of multilingualism in Lithuania in general, there is also a high level of multilingualism among Karaim speakers. Karaim speakers also communicate with the dominant languages of their respective regions, including Lithuanian, Polish, and Russian. Some also have religious knowledge of Hebrew (Csató 2001). Multilingualism is a necessity for Karaim speakers, because without other languages the majority would not even be able to communicate with members of their own family (Csató 2001). Most dialects of Karaim are now extinct. Maintenance of the Karaim language in Lithuania is now endangered due to the dispersal of Karaim speakers under the Soviet regime in the aftermath of World War II and the very small number and old age of fluent speakers remaining (Csató 2001). Children and grandchildren of Karaim speakers speak Lithuanian, Polish, or Russian, and only the oldest generation still speaks Karaim. While most languages of the Turkic family exhibit palatal vowel harmony, Trakai Karaim shows harmony in palatalization of consonants. Thus, in any given word, only palatalized or only non-palatalized consonants can be found (Németh 2003). Palatalized consonants occur in the presence of front vowels, and non-palatalized consonants occur in the presence of back vowels. Similarly to most Turkic languages, virtually all of the consonants in Karaim exist in both a palatalized and a non-palatalized form, which may be further evidence of their genetic relationship (Hansson 2007).
