Judaism/Common Jewish Expressions
Jewish culture covers an extensive number of languages and dialects. Throughout history, it was common for Jews to codeswitch between one or more Jewish languages and the non-Jewish languages they might encounter. Most Jewish dialects and languages are written in Hebrew script and can be demonstrated to each contain numerous Hebrew and Tanakhic influences on linguistic factors such as vocabulary and tone, reflecting their common origin. While not all Jews are religious, practically all contemporary Jewish culture can find religious and spiritual influence in its roots.

"The Yod, The Hey, the Vav, the Hey" a way of referencing the tetragammaton without invoking and disrespecting this divine name, sanctified in the Torah and forbidden from being erased or defaced. This is an important principle to many observant Jews. The names of God are regarded with increasing sanctity the closer they approach the true name of God. This name is treated with utmost sanctity, second only to the true name. Kabbalah indicates that a Golem can be created by the act of speaking the true name, which due to its many syllables requires several hours of intense concentration and reportedly carries mortal consequences for making a single mistake.
Yoshke - a dismissive name for Jesus, who is believed to be neither divine nor a prophet.
