 The Catalan rabbi and Talmudist, Menachem Meiri (1249 – c. 1310), also brings down an exhaustive list of words in his "Kiryat Sefer", showing which words are to be written by scribes in "plene scriptum" and which words are to be written in "defective scriptum", based on the Masoretic Text.Rabbi Jedidiah Norzi (1560–1626) wrote a popular work on Hebrew orthography contained in the Five Books of Moses, and in the five "Megillot", with examples of "plene" and defective writings, which was later named "Minḥat Shai".In the "Tikkun Soferim" (the model text for copying Torah scrolls by scribes), the word "plene" is always used in relation to other words written in "defective scriptum", not because there is necessarily anything unusual or abnormal about the word being written in such a way, but to ensure a universal layout (conformity) in scribal practices, where one word in a text must be written as though it were lacking in "matres lectionis", and another word in a different text (sometimes even the same word) appearing as though it was not.
