(serum)
clear blood fluid
Etymology
'serum' originates from Latin, specifically the word 'serum', where 'serum' meant 'whey' or 'watery fluid'.
'serum' entered English from New Latin/Late Latin 'serum' (used in scientific and medical contexts) and eventually became the modern English word 'serum'.
Initially, it meant 'whey' (the watery part of milk), but over time it evolved into its current meaning of 'the clear liquid part of blood or other bodily fluids; also medicinal or cosmetic liquid preparations'.
