Etymology
Etymology Information

'retrodate' originates from modern English, specifically formed by combining the Latin prefix 'retro-' and the word 'date' (ultimately from Latin 'datum'), where 'retro-' meant 'back(wards)' and Latin 'datum' meant 'something given'.

Historical Evolution

'retrodate' was created in English by attaching the Latin combining form 'retro-' (meaning 'back') to the existing word 'date' (from Old French 'date', from Latin 'datum'), producing a verb meaning 'to make dated earlier'.

Meaning Changes

Initially, the formation meant 'to give a date that is back (earlier),' and over time it has remained focused on assigning or regarding an earlier date (i.e., backdating).
