'unsubmitted' originates from the prefix 'un-' meaning 'not' and the verb 'submit', which comes from Latin 'submittere', where 'sub-' meant 'under' and 'mittere' meant 'to send'.

'submittere' transformed into the Old French word 'soumettre', and eventually became the modern English word 'submit'.

Initially, 'submit' meant 'to send under', but over time it evolved into its current meaning of 'to present for consideration'.
