'stocky' originates from the Middle English word 'stokke,' which meant 'tree trunk or log,' reflecting the solid and sturdy nature of the word.

'stokke' transformed into the modern English word 'stocky' through the influence of the word 'stock,' which also refers to a solid base or foundation.

Initially, it meant 'resembling a tree trunk,' but over time it evolved into its current meaning of 'having a broad, solid, and sturdy form.'
