What does cruddle mean?
Cruddle is a rare English verb meaning to curdle — that is, for a liquid such as milk to thicken and separate into soft lumps. Functioning as an intensified or frequentative form built on 'crud', it describes the same process as the everyday word 'curdle', though it survives today only in dialectal, rural, or deliberately old-fashioned speech rather than in standard usage. A farmer might say that cream left too long in the warm churn has cruddled, or a cook might find that sauce has cruddled after overheating. The word can also be applied figuratively, as when a person's stomach is said to cruddle at an unpleasant thought. Because it is uncommon, writers who reach for it usually do so for local colour or comic effect, and readers unfamiliar with it can safely take it as a synonym of curdle. Its rarity makes it a curiosity of English vocabulary rather than a word needed in ordinary conversation.

Etymology of cruddle
Cruddle derives from 'crud' — an old word for curd — combined with the frequentative suffix '-le' found in verbs like 'sparkle' and 'crackle'. It thus belongs to the same family as 'curd' and 'curdle', which themselves trace back through Middle English 'crud' to notions of coagulated matter. The word appears chiefly in British and American dialect writing of recent centuries and never displaced its sibling 'curdle' in mainstream use.
