1. Know that there are nouns from this class that occur with an added mem at the beginning and a tav at the end, such as maskit and marbit; and others with a tav both at the beginning and at the end, such as tavnit and takhlit.

2. Know that these forms ought properly to be marbiyyit and tavniyyit, with three yods. One yod is the connective yod, like the one that appears after the third radical in the participle of the hifʿil pattern (as in mafqid → mafqidah). The second yod stands in place of the final he of the root, since their roots are ravah and banah. The third is the yod of relation, as in ʿivrit (“Hebrew”) and mitsrit (“Egyptian”). All of these form their plurals with a mobile yod, following the pattern ḥamishiyyot, as I wrote in the Third Treatise, Principle Thirteen. I will speak of these further in my book on composition, under the word mavligiti.

3. Some are also found in this pattern in which the final vowel is shuruk, and this occurs specifically with tav at the beginning, such as tarbut (“increase, culture”) and taznut (“fornication”). One example is found with mem: anshei matsotekha (“the men of your contention,” Isa. 41:12); the independent form from this is matsut, which properly would have been menatsut, since its root is natsah. Likewise in the language of the Mishnah: malkot (“lashes”), from laka.

4. Remember that the mem and the tav at the beginning of these forms are always pointed with pataḥ, even when there is no guttural letter causing it. One example is also found with an added aleph at the beginning: aḥoti baʾozneikhem (“my declaration in your ears,” Job 13:17), whose root is ḥavah. The general rule is that every noun you find with mem or tav at the beginning with either ḥiriq or pataḥ, and whose following letter has a sheva, and which does not belong to the class of regular (strong) roots—that is, it does not have three fully vocalized radicals—belongs to the class of verbs whose final radical is he. Only two examples are found with tav at the beginning and a sheva, namely teʿalah (“trench,” 1 Kings 18:32) and telaʾah.
