curd
Word family
Synonym discussion
Sense: noun/1
These four words name different stages and outcomes of the same milk transformation. Curd is the thick white solids that separate from milk when it sours; whey is the watery yellowish liquid left behind in the same process — the two are produced together. Cheese is what curd becomes once it has been pressed, salted, and often aged; cheese is a finished food, curd is the intermediate substance. Yogurt is a different result of fermenting milk, kept as a creamy semi-solid without being separated into solids and liquid. So: milk + souring agent → curd + whey; curd + pressing/aging → cheese; milk + bacteria culture → yogurt (no curd / whey split).

Etymology
First recorded in Middle English around 1350 as 'crud', meaning a coagulated substance. The 'r' and 'u' switched places (a process called metathesis) to give the modern spelling 'curd' by the 1500s. The ultimate origin before Middle English is unclear — possibly related to a word for 'press' or 'squeeze together'.
