The word of the week is peck. You probably already new it meant to nip or pick up with a beak or a hasty kiss.
Did you know a peck is also a unit of measurement for dried goods? I did, but had thought it was a tiny and vague amount (like a pinch or a sprinkle). Actually it's 1/4 of a bushel.
Still none the wiser? That's two gallons or around nine litres.
