backrun
|back-run|
/ˈbæk.rʌn/
follow after to gain
Etymology
'backrun' originates from Modern English, specifically a compound of the words 'back' and 'run', where 'back' ultimately derives from Old English 'bæc' meaning 'back' and 'run' derives from Old English 'rinnan' meaning 'to run'.
'backrun' changed from a hyphenated or separable form 'back-run' (a direct compound of 'back' + 'run') and developed into the closed compound 'backrun' in modern usage; its components trace to Old English elements 'bæc' and 'rinnan'.
Initially it would have simply meant 'to run backward' or 'to run behind', but over time it has acquired a specialized modern sense of 'to follow another transaction to profit from it' (especially in finance/crypto contexts).
