كُلُّ اسْمٍ — Translation: “every noun.”
The syntactic role of a fāʿil depends on its relationship within the sentence, not on whether it names a human. An explicit noun can be the fāʿil, as زَيْدٌ in قَامَ زَيْدٌ; a pronoun can also occupy the subject role, as the tāʾ in قُمْتُ. The book’s introductory wording states the core rule; pronoun details belong to further discussion.
