You may have emptied a sacco della spazzatura ('garbage bag'), picked up a sacco di farina ('bag of flour') and been asked whether you'd like a sacchetto to carry it in (the diminutive form, 'little bag', is used for plastic bags). Aside from its everyday use, sacco also features in various Italian expressions: if you spot someone doing something they shouldn't, you can prendere qualcuno con le mani nel sacco (literally 'catch someone with their hands in the bag', or as we'd say, 'catch them red-handed') – or if you're the one who needs to confess, you might vuotare il sacco ('empty the bag' or more colloquially, 'spill the beans').
