agger - n., a double tide; (Roman arch.) an embankment or rampart.
The former being either a high tide where the water rises to a certain level, recedes, then rises again, or a low tide where the water recedes to a certain level, rises slightly, then recedes again. In both senses, from Latin, from aggerere, to heap up.
