empty: [OE] The original meaning of Old English ǣmtig appears to have been ‘unoccupied, at leisure’, and it was only secondarily that it developed the physical connotations of ‘not full’ which have come down to us in empty. (It also meant ‘unmarried’.) It was a derivative of the noun ǣmetta ‘rest, leisure’. This is a word of uncertain history, but it has been plausibly analysed as the negative prefix ǣ- plus a derivative of the root which produced modern English mete (as in ‘mete out’), meaning something like ‘not assigned’. => mete
