In a flat state or position; lying flat or completely level.
From 'a-' (in the state of) + 'flat,' combining the archaic intensive prefix with the common adjective describing something level or without elevation.
Words like 'aflat' show English's lost verbal prefix system—centuries ago, 'a-' created continuous or state-based meanings (think 'afire' or 'asleep'), but we've mostly dropped this pattern, keeping only fragments.
