'accidentally-empty' originates from the combination of 'accidentally' and 'empty', where 'accidentally' comes from Latin 'accidentalis', meaning 'happening by chance', and 'empty' from Old English 'æmtig', meaning 'at leisure, unoccupied'.

'accidentally' changed from the Latin word 'accidentalis' and 'empty' from Old English 'æmtig', eventually forming the modern English compound word 'accidentally-empty'.

Initially, 'accidentally' meant 'happening by chance', and 'empty' meant 'unoccupied'. Together, they evolved to describe something unintentionally devoid of contents.
