Cream or the thick, rich part of milk; also used in pharmacy to describe a thick medicinal substance.
From Latin cremor, meaning cream or thick juice, related to the verb cernere (to sift or separate). The Romans noticed that cream separated from milk and named it for this property.
In pharmacology, 'cremor' is a technical term for a specific texture—thicker than a lotion but not quite a true cream—showing how old Latin terms persist in specialized fields because they describe precise physical properties.
