Meaning and usage of the word lobe in English

The word "lobe" derives from the Old French word "lobe" meaning "lump" or "mass", which in turn originated from the Latin "lobus" meaning "bittle piece", potentially referring to a piece that has been bitten off. Interestingly, the Latin word "lobus" also has another meaning, "feather", possibly due to the resemblance of the feathers of a bird to the segmented shape of a lobe. The anatomical usage of the word "lobe" for the division of organs, such as the brain or lungs, began in the 16th century and has since become widely accepted in medical terminology. Overall, the etymology of the word "lobe" reveals its origin as a descriptive term for a distinct, shaped section of something larger.
