means A shaped mass of bread baked as a single unit, or by extension any block-shaped quantity of food — and as a verb, to idle away time doing nothing in particular.

from From Old English 'hlaf,' meaning bread, which is one of English's oldest and homeliest words — it gave us 'lord' (originally 'hlafweard,' the loaf-keeper or bread-guardian) and 'lady' ('hlafdige,' the loaf-kneader). It has cousins across the Germanic family, like German 'Laib.' The lazy sense — to 'loaf about' — is a separate and later arrival, possibly borrowed from German 'Landläufer,' a vagabond or tramp who wanders the land.
