lobe
[C] Countable
pl: lobes
The word carries a clinical and anatomical tone, evoking an image of soft, fleshy, or organic segments. It is used almost exclusively in biological or medical contexts to describe the natural partitioning of an organ. While it describes a physical shape, the term suggests a functional separation. In the brain, a lobe is not just a bump but a distinct region responsible for specific neurological tasks, whereas in the ear, it refers to the soft, non-cartilaginous lower portion.
Countable when referring to the individual anatomical segments of an organ, such as the two lobes of the lungs or the various lobes of the brain.
