'trade-related' originates from the combination of 'trade' and the suffix '-related', where 'trade' meant 'the action of buying and selling goods and services' and '-related' meant 'connected with'.

'trade' changed from the Old English word 'træd' meaning 'path' or 'course', and eventually became the modern English word 'trade'.

Initially, 'trade' meant 'path' or 'course', but over time it evolved into its current meaning of 'the action of buying and selling goods and services'.
