"The use of Judeo-Persian language can be traced back to the sixth century B.C., but there are no literary documents preserved in this language prior to the eighth century A.D." "Although Judeo-Persian has many linguistic features in common with Modern Persian, it contains many peculiarities including the following: 1. The usage of loanwords from Hebrew, Arabic and Aramaic languages. It should be pointed out, however, that some Judeo-Persian works are devoid of these loanwords and are entirely in standard classical Persian written in Hebrew script. (e.g., Shahin Shirazi's poems). 2. Substantial spelling, phonetic, and syntax differences. 3. Preservation of many archaic Persian words. 4. Retention of many archaic grammatical and phonetic fea? tures not found in Modern Persian. 5. Extensive usage of colloquial style"
