tills

Till is an unsorted glacial sediment deposited directly by a retreating glacier. Till is typically unstratified and contains particles ranging from clay to boulders, reflecting the bedrock encountered by the ice. The proportion of gravel, sand, silt, and clay varies from deposit to deposit, and the sediment often includes large clasts known as erratics. Because tills are not reworked by meltwater, they contrast with stratified drift shaped by running water. In geomorphology, tills help identify former glaciations and are commonly associated with moraines, ground moraines, and diverse landscape features. The term tills can be used to refer to multiple deposits across regions or glaciations.

In commerce, a till (plural tills) is the cash drawer or cash register compartment at a checkout; it stores coins, banknotes, and receipts. In many setups a till is part of a point-of-sale system, and several tills may operate in a single store. Cash handling procedures include regular counting, reconciliation of cash with sales totals, and secure locking.

As a verb, to till means to cultivate or plow soil. The third-person singular present tense is tills. Tillage refers to the cultivation practices used to prepare seedbeds, control weeds, and mix in organic matter. The word has a long history in agriculture and farming contexts.
