'uninterruptedly' originates from 'un-' meaning 'not', 'interrupted' from Latin 'interrumpere', where 'inter-' meant 'between' and 'rumpere' meant 'to break'.

'uninterruptedly' changed from the Latin word 'interrumpere' and eventually became the modern English word 'uninterruptedly'.

Initially, it meant 'not broken between', but over time it evolved into its current meaning of 'without interruption'.
