Soaked or thoroughly wet; in a state of being soaked with liquid.
From 'a-' plus 'soak,' where 'soak' comes from Old English 'socian,' possibly from Germanic roots related to sucking or drawing in. It became the standard verb for thorough wetting.
In a world before washing machines, 'asoak' was probably used constantly—'leave the clothes asoak overnight'—and it's a reminder that these 'a-' words weren't poetic at all, but everyday practical language that has just completely disappeared.
