In an attentive, aware, or intentional manner; while paying attention or with full knowledge.
From 'advertent' (attentive, aware) + '-ly' suffix. This adverb form describes the manner in which an action is performed—specifically, in a deliberate or aware manner rather than accidentally.
The opposite 'inadvertently' is much more common in modern English, but 'advertently' reminds us that most actions exist on a spectrum from completely careless to completely deliberate—and that distinction matters legally and morally.
