施恩 means 'to bestow kindness or favor' — literally, 'to apply (施) benevolence (恩)'. The character 施 conveys the idea of carrying out, exerting, or imparting something tangible or intangible, while 恩 refers to grace, favor, or deep kindness — often with moral or relational weight, such as gratitude owed or compassion freely given. Together, they describe an intentional, generous act of helping or benefiting another, typically by someone in a position of power, authority, or moral superiority.

This term carries a formal, slightly literary tone and is often used in classical or semi-formal contexts — such as historical narratives, moral essays, or speeches about virtue and leadership. It implies asymmetry: the giver confers unearned goodwill, and the receiver may feel indebted. Unlike casual kindness (e.g., 帮忙), 施恩 suggests depth, intentionality, and sometimes even condescension if misapplied — making register awareness essential for learners.
