The present participle of 'assent'; the act of agreeing or expressing consent to something.
From Latin 'assentire' (to agree). The '-ing' suffix transforms the verb into its continuous form, describing an ongoing action of agreement.
In parliamentary records and contracts, 'assenting' became the official term for how people formally agreed to laws and treaties—it's the language of institutional agreement, giving individual consent a kind of official weight.
