'large-built' originates from the combination of 'large' and 'built', where 'large' means 'big in size' and 'built' refers to 'constructed or formed'.

'large' and 'built' have been used in English since the Middle Ages, and their combination into 'large-built' is a modern English formation.

Initially, 'large' meant 'big in size' and 'built' referred to 'constructed', and together they have maintained the meaning of 'having a large and sturdy physical structure'.
