Crudo is Spanish for “raw,” particularly in the everyday sense of “uncooked food”.
From the Latin crudus, meaning the same (raw, bloody), we get various English words including:
All still contain the cr- prefix, and crude still has the following -d- as well.
Interestingly, the Latin crudus itself comes from the Indo-European *kreue also meaning “raw”, from which — with the initial k- sound lost — we get the word raw itself. Thus, even raw itself is related to crudo.
