'fetch' originates from Middle English 'fechen', which in turn derives from Old English forms (such as 'feccean' / 'feccan') meaning 'to bring' or 'to seize'.

'fetch' changed from Old English forms into Middle English 'fechen' (or variants) and eventually became the modern English word 'fetch'.

Initially it meant 'to bring or seize', and over time the core sense 'go and bring' was retained; additional senses developed, such as 'to fetch a price' and the noun sense of a supernatural 'double'.
