'standard-built' originates from the combination of 'standard' and 'built', where 'standard' refers to a level of quality or attainment and 'built' refers to the physical structure or physique.

The term 'standard-built' evolved from the use of 'standard' to describe common or typical qualities and 'built' to describe physical structure.

Initially, it meant 'constructed according to a standard', but over time it evolved into its current meaning of 'having a typical physique'.
