To predict or indicate something about the future; to foretell or act as an augur.
From Latin 'augurari' (to divine or foretell), related to 'augur'. The verb form allows the action of divination or future-telling to be expressed.
Using 'augurate' today sounds wonderfully archaic—it means to play the role of a soothsayer, so calling something an 'augurating sign' suggests it's mysteriously predicting what's to come!
