'transiently-kept' originates from the Latin word 'transientem,' where 'trans-' meant 'across' and 'ire' meant 'to go,' combined with the English word 'kept,' which is the past participle of 'keep.'

'transientem' transformed into the English word 'transient,' and eventually combined with 'kept' to form 'transiently-kept.'

Initially, 'transient' meant 'passing quickly,' and this meaning has largely remained the same in modern usage when combined with 'kept.'
