Crud is dirt, grime or unwanted residue. It is a metathesised form of *curd*, meaning the letters swapped places, and in Middle English the two were interchangeable words for coagulated milk. Only later did *curd* keep the food and *crud* take the filth. The same letter-swapping produced *bird* from *brid* and *third* from *thridda*. American military slang revived *crud* in the twentieth century, and computing uses it for junk data.
