'unforeseen-location' is a compound word formed from 'unforeseen' and 'location'. 'Unforeseen' originates from Old English, specifically the word 'unforseon', where 'un-' meant 'not' and 'forseon' meant 'to see'. 'Location' comes from Latin, specifically the word 'locatio', where 'locare' meant 'to place'.

'unforeseen' changed from the Old English word 'unforseon' and eventually became the modern English word 'unforeseen'. 'Location' transformed from the Latin word 'locatio' and eventually became the modern English word 'location'.

Initially, 'unforeseen' meant 'not seen or anticipated', and 'location' meant 'a place or position'. The compound 'unforeseen-location' retains these meanings, referring to a place not anticipated.
