scrawny

The adjective 'scrawny' emerged in American English in the early 19th century. Its origins are somewhat obscure but it is believed to be a variant of the dialectal English word 'scrawny', which itself may be an alteration of 'scranky', meaning thin or stunted. A plausible connection is to the Old Norse word 'skrælna', meaning to shrivel or dry up, suggesting a deep-rooted association with a withered, shrunken state. This etymological journey from a concept of shriveling to describing a lean, bony physique illustrates the typical semantic shift from a general physical process to a specific descriptive attribute.

The word 'scrawny' is a simplex word of uncertain origin, likely a blend or variant of dialectal English words. It is not productively formed from clear, separable morphemes in modern English.
