Recrudesce comes from Latin recrudescere ('to become raw or sore again, break out afresh'), from re- ('again') + crudescere ('to grow worse'), from crudus ('raw, bloody'). The historical chain includes Latin re-, Latin recrudescere, and Latin crudus. Older glosses in the chain include "to become raw or sore again, break out afresh", "again", "to grow worse", and "raw, bloody", which help explain the semantic range of the modern word. Morphologically, recrudesce is best read as compound and borrowing, yielding an English verb shaped by both form history and later usage. In current English it functions as a verb, with the sense "to break out or become active again after a period of dormancy". English derivatives include recrudescence, recrudescent, and recrudescing; related forms include crude and cruel. The result is an English verb whose etymology preserves the older forms while supporting the word's specialized modern meaning.
