Etymology
Etymology Information

'lobe' originates from Greek, specifically the word 'lobos', where 'lobos' meant 'a rounded projection or an inflated/rounded part'.

Historical Evolution

'lobe' passed into Latin as 'lobus', entered Old French as 'lobe' or similar forms, and then into Middle English to become the modern English 'lobe'.

Meaning Changes

Initially it denoted a rounded or swollen projection; over time the word retained this general sense and became specialized in anatomy and botany to mean a subdivision or rounded projection of an organ or leaf.
