Explanation of the statement of Ibn Malik (may Allah have mercy on him): *Zanna* and its sisters.

The Shaykh : When the author, Ibn Malik (may Allah have mercy on him), finished in his *Alfiyyah* mentioning the opposing *nawasi* (verbs that change the case of the subject and predicate), namely *kana* and its sisters and *inna* and its sisters—where *kana* and its sisters raise the subject and put the predicate in the accusative case, while *inna* and its sisters put the subject in the accusative case and raise the predicate, so the effect of these two is opposite—he came to the third type of *nawasi*, or the third category, which is that which changes both the subject and the predicate, putting both in the accusative case. We do not have a fourth category that raises both the subject and the predicate, because if the subject and predicate remain in the nominative case, there is no *nasikh* (verb that changes the case).
The author said: " *Zanna* and its sisters"
"Its sisters" means those that share its grammatical function, just as with *kana* and its sisters and *inna* and its sisters.
