The act of putting a bonnet on someone or something; decorating or covering with a bonnet.
From 'bonnet' as a verb (to place a bonnet on) plus the present participle suffix '-ing', creating the gerund form for the action of bonneting.
The verb 'to bonnet' and its gerund form show how English once turned every noun into an action—people didn't just wear bonnets, they actively 'bonneted' themselves in a deliberate, conscious act!
