single-cell

the compound adjective 'single-cell' is a modern scientific term built from two english words of latin origin. 'single' traces back to latin singulus, meaning one or individual, which itself may derive from proto-indo-european sem- (one). 'cell' originates from latin cella, meaning a small room or chamber, a term adopted by scientist robert hooke in the 17th century to describe the microscopic compartments he observed in cork. the literal combination, 'one chamber', perfectly captures the modern biological meaning: pertaining to or consisting of just one of these fundamental units of life, as opposed to multicellular organisms.
