Referring to the liver as an internal organ in medical, biological, or health contexts.
Standard term for the liver organ. Used in medical, anatomical, and everyday health contexts.
I'm studying the function of the liver.

Sometimes used for liver as food, especially in traditional contexts or set phrases like 肝焼き (grilled liver).

Used in many idioms meaning 'guts', 'courage', or 'nerve'. Often paired with 据える (to settle) or 太い (thick).
He has nerves of steel. (lit. His liver is settled.)
He's a bold person. (lit. A person with a thick liver.)
Colloquial term for 'guts' or 'courage', literally 'liver ball'. Often used in 肝っ玉母さん (tough, big-hearted mother).
Use 肝臓 for the organ in medical/health contexts. Use レバー for food. 肝 can be used in both but is more common in idioms and traditional food names. Using レバー for the organ sounds unnatural, and using 肝臓 for food is overly clinical.
