means A cash drawer or small money box in a shop where coins and notes are kept during the day's business.

from From Middle English 'tillen' or 'tylle,' meaning a small drawer or compartment for valuables. The word for the cash version is the same one — a little drawer set aside to hold money — though its deeper roots are murky, possibly tied to an old verb for drawing out or pulling. Worth noting: this 'till' has nothing to do with the farmer's 'till' (to plough soil) or the conjunction 'till' (meaning 'until'); these are three separate words that happened to land on the same spelling, like strangers sharing a name.
