The term 'per se fecit' translates to 'he/she/it made by itself' and is often used to discuss actions that are reflexive in nature. In Latin grammar, it highlights how a subject performs an action on itself, which is crucial when examining the role of reflexive pronouns. Understanding this concept helps to grasp how certain verbs in Latin signify self-directed actions, often requiring specific pronouns to convey that the subject is both performing and receiving the action.
