curdled

The word 'curdled' traces its lineage to the Middle English noun 'crudde', which denoted the coagulated part of soured milk. The addition of the frequentative suffix '-le' transformed it into the verb 'curdle', describing the process by which milk separates into curds and whey. The final '-d' marks its common usage as the past participle, which then functions adjectivally to describe the state resulting from that process. Thus, the term's logic flows directly from the physical substance ('curd'), through the action of forming it ('curdle'), to the final, often undesirable, solidified state ('curdled').
