'allentato' originates from Italian, specifically the word 'allentare,' where 'al-' meant 'to' and 'lentare' meant 'to loosen.'

'allentare' transformed into the Italian adjective 'allentato,' and it has been adopted into English usage in specific contexts.

Initially, it meant 'to loosen,' but over time it evolved into its current meaning of 'loose or slack.'
