Etymology

Origin of cell

First recorded before 1150; 1665–75 cell for def. 4; Middle English celle, from Old French celle, from Medieval Latin cella “monastic cell,” Latin: “room”; Old English cell, from Medieval Latin, as above; see cella

Explanation

Cell has several different meanings, but all of them are similar. Whether it's in a prison or in your blood (or even in the political landscape), a cell is a small room, space, or unit. Blood is composed of countless individual cells, as are virtually all of the organs of the body: skin, liver, lungs, brain, etc. The cell is the basic unit of all biology. A cell in a prison is the room in which a prisoner lives. But did you know that a cell can also be a small group of people devoted to a larger political cause? The government's security forces are constantly on the lookout for terrorist "sleeper cells" and would love to get the members of a sleeper cell into a prison cell.
