'intentionally-lost' originates from the combination of 'intentionally,' derived from Latin 'intentio,' meaning 'a stretching out,' and 'lost,' from Old English 'losian,' meaning 'to perish.'

'intentionally' combined with 'lost' to form the modern English term 'intentionally-lost.'

Initially, 'intentionally' meant 'with intention or purpose,' and 'lost' meant 'misplaced or not found.' Together, they evolved to mean 'deliberately misplaced or hidden.'
