IPA: /ˈʌm.boʊ/
KK: /ˈʌmboʊ/
A small raised area or projection on a surface, often found in anatomy or biology, such as on the eardrum or a bivalve shell.
The umbo of the eardrum can be seen during a medical examination.
Umbo comes from Latin 'umbo' (meaning a rounded projection or boss). The word refers to a rounded part or knob, often used in the context of shields or other objects.
Think of a rounded 'projection' or 'boss' when you hear umbo, as it describes a rounded part that sticks out.
