the body's resignation letter, written in yawns and submitted to a boss who never reads it
means the state of being tired, drained, or worn down — whether in body, mind, or patience.
from From Old English wērig, meaning 'tired' or 'exhausted,' which gave us the adjective weary; the abstract noun was built by adding the familiar '-ness' suffix that turns a quality into a thing you can carry around. The root is possibly tied to an older Germanic sense of 'wandering' or 'stumbling,' as though weariness were the heaviness of having walked too far — a cousin, perhaps, to the dazed footsteps of someone worn out by the road.
