Notarikon

Notarikon (Hebrew: נוטריקון‎ Noṭariqōn) is a method of deriving a word, by using each of its initial (Hebrew: ראשי תיבות‎) or final letters (סופי תיבות‎) to stand for another, to form a sentence or idea out of the words. Another variation uses the first and last letters, or the two middle letters of a word, in order to form another word. The word "notarikon" is borrowed from the Greek language (νοταρικόν)), and was derived from the Latin word "notarius" meaning "shorthand writer."

Notarikon is one of the three ancient methods used by the Kabbalists (the other two are gematria and temurah) to rearrange words and sentences. These methods were used in order to derive the esoteric substratum and deeper spiritual meaning of the words in the Bible. Notarikon was also used in alchemy.

Rashi uses notarikon seven times in his pirush (פירוש‎, "explanation") on Chumash:

A common usage of Notarikon in the practice of Kabbalah, either for magic or ritual, was to form secret names of God derived from religious or biblical verses. Agla, an acronym for Atah Gibor Le-olam Adonai, translated, "You, O Lord, are mighty forever," is one of the most famous examples of Notarikon. Dozens of examples are found in the Berit Menuchah, as is referenced in the following passage:
