Tikkun (book)

A tikkun or tiqqun (Hebrew: תיקון) is a book used by Jews to prepare for reading or writing a Torah scroll.

A tikkun kor'im or tiqqun qor'im (readers' tikkun) is a study guide used when preparing to chant [lein] the Torah reading from the Torah in a synagogue.

People who chant from the Torah must learn the tune and the pronunciation of the words beforehand, as the scroll itself has neither points nor cantillation marks, and because there are places where the word to be read (the qere) differs from that written (the kethib) in the scroll.

A tiqqun soferim (scribes' tikkun) is similar, but is designed as a guide or model text for scribes writing a copy of the Torah by hand.

For instance, it helps the scribe to know how many letters there are per line, so a tikkun soferim gives the size of each line, measured in yud-widths (because yud is the smallest Hebrew letter).
