'augurer' originates from Latin, specifically the word 'augur', where 'augur' meant 'one who interprets omens' or 'diviner'.

'augurer' changed from Latin 'augur' into Medieval/Old French forms (e.g. 'augur') and entered Middle English as 'augur'/'augurer', eventually becoming the modern English 'augurer'.

Initially it meant 'a (Roman) official who interpreted omens', but over time it evolved into the more general meaning 'a person who predicts or foretells events'.
