unshelled

The word 'unshelled' is a transparent Modern English formation built upon the ancient Germanic root for a hard covering. The core noun 'shell' descends from Proto-Germanic skaljō, related to the concept of a scale or a fragment, which itself can be traced to the Proto-Indo-European root (s)kel- meaning "to cut" or "split," reflecting how shells like those of nuts or eggs are often broken open. The addition of the native English negative prefix 'un-' and the participial suffix '-ed' follows a straightforward and productive pattern in the language, creating an adjective that literally means "not having been shelled" or "not possessing a shell." This logical construction allows the word to describe anything from nuts and peas to shrimp or even abstract concepts lacking a protective layer, maintaining a clear semantic link to its physical origins.
