Fiss- means 'Split'.

Fiss- means 'Split'.

• A. Fence
• B. Machine
• C. Split
• D. Turn

Answer: (C)

The meaning to focus on is split. In medical terminology, the root fiss- comes from a idea of breaking or dividing. You’ll see it in words like fissure, which refers to a crack or split in tissue, and even related terms like fission in other sciences, which centers on splitting. So the option that matches this concept—split—is the best fit. The other ideas don’t align with the root. A fence is a barrier, not a split; a machine is a device or mechanism; a turn refers to rotation. None of those convey the sense of dividing or cracking that fiss- implies.
