A short Sofer STaM glossary

Sofer STaM

A trained, certified Jewish scribe authorized to write and inspect Sifrei Torah, Tefillin, and Mezuzot. STaM is the acronym for these three: Sefer Torah, Tefillin, Mezuzah.

Mezuzah

The small parchment scroll, hand-written by a sofer, that is affixed to the doorposts of a Jewish home. The case is just the holder — the mitzvah is the scroll inside.

Tefillin

Two leather boxes containing four hand-written parchment passages, worn by Jewish men on the head and arm during weekday morning prayer.

Klaf

The parchment used for mezuzot, tefillin, and Torah scrolls. It is prepared from the hide of a kosher animal, by hand, following specific halachic steps. The klaf is what gets examined during a professional mezuzah inspection.

Ktav

The style of script used by the sofer. Miami Mezuzah Center offers Sephardi, Ari Zal, and Chabad ktav. Families typically choose the ktav that matches their community or rabbi's custom. All three are equally kosher when written correctly by a certified sofer STaM.

Kasher / Kosher

Fit for use. A scroll that meets every halachic requirement.

Pasul

Invalid. A scroll that is missing a requirement — a cracked letter, faded ink, or another disqualifying issue. If a scroll is found pasul during a mezuzah inspection, replacement options are explained without pressure.

Tikkun

A repair. Some issues found during inspection can be corrected by a sofer; others cannot. Rabbi Levi will tell you honestly which category a scroll falls into.

Parshiyot

The four Torah passages written on parchment and placed inside the tefillin boxes. They are written separately and must be in correct order.

Batim

The black leather boxes of the tefillin that house the parshiyot. The batim themselves have detailed halachic requirements — squareness, paint, stitching.

Retzuot

The black leather straps of the tefillin. They must be black on the outside and made from the hide of a kosher animal.

Shel Yad / Shel Rosh

The arm tefillin (Shel Yad) and the head tefillin (Shel Rosh). Each contains its own parshiyot and has its own halachic requirements.

Magihah

A trained checker who examines scrolls after they are written, looking for missing or malformed letters. A serious sofer always has his work reviewed by a second pair of eyes before it is sold — and the magihah's role continues later, in every Miami mezuzah checking a family schedules.

Hagahah

The checking process itself — a careful, letter-by-letter examination of a scroll by eye.

Kal v'chomer in scrolls

A simple principle Rabbi Levi often shares: if a scroll has even one disqualifying letter, the entire mezuzah or pair of tefillin is not kosher. That is why a quick visual glance is never enough.
