Yeshivish
Yeshivish, also known as Yeshiva English, Yeshivisheh Shprach, or Yeshivisheh Reid, is a sociolect of English spoken by Yeshiva students and other Jews with a strong connection to the Orthodox Yeshiva world.
"Yeshivish" may also refer to non-Hasidic Haredi Jews. Sometimes it has an extra connotation of non-Hasidic Haredi Jews educated in yeshiva and whose education made a noticeable specific cultural impact onto them. In the latter case the term has ambivalent connotations comparable to those of the term "academic".
James Lambert writes that the term may be a portmanteau word of yeshiva and English, or may simply be formed from yeshiva + the adjectival suffix -ish.
Research
The first serious study about Yeshivish is a master's thesis by Steven Ray Goldfarb called "A Sampling of Lexical Items in Yeshiva English." The work lists, defines, and provides examples for nearly 250 Yeshivish words and phrases. The second, more comprehensive work is Frumspeak: The First Dictionary of Yeshivish by Chaim Weiser. Weiser maintains that Yeshivish is not a pidgin, creole, or an independent language, nor is it precisely a jargon. Baumel following Weiser notes that Yeshivish differs from English primarily in phonemic structure, lexical meaning, and syntax.Benor offers a detailed list of distinctive features used in Yeshivish. Katz describes it in Words on Fire: the Unfinished Story of Yiddish as a "new dialect of English", which is "taking over as the vernacular in everyday life in some... circles in America and elsewhere". Heilman and others consider code-switching a part of Yeshivish. Though Kaye would exclude English speakers in the context of a Yeshiva, studying the Talmud, from code-switching where he considers the terms "Yiddish English" or "Yiddishized English" may be more appropriate.
Patterns of usage
Yeshivish is primarily a male-spoken dialect. Fathers and sons, particularly of teenage years and above, might speak Yeshivish, while mothers and daughters generally speak a milder variety of it, which generally features Yeshivish phonology but excludes many Talmudic words. This can be explained as much of the Yeshivish lexicon is learned in Yeshiva where the studying takes place using a specialist nomenclature. Familiarity with these terms develops and they are then re-applied to other situations. There is a higher incidence of Yeshivish being spoken amongst Orthodox Jews that are regularly involved in Torah study, or belong to a community that promotes its study.Commonly used platitudes among Orthodox Jews are frequently expressed with their Yeshivish equivalent. Examples include using shkoyakh or shkoyekh for an expression of appreciation: "bravo" or "good job", or "thank you", a contraction from the Hebrew "Yishar Ko'ach", which literally translates as "May your strength be firm" and is used to indicate to someone that they have done a good job, and Barukh HaShem, meaning "Blessed is HaShem ". Yeshivish dialogue may include many expressions that refer to HaShem.
