2323: auspice, auspicious, & augur Apr 28, 2021

'Auspice' on its own is a legitimate albeit rare word, but referring to a prophetic object or sign, but in the phrase "under the auspices of..." meaning "with the support and oversight of..." it's fairly common. It is in the first way, unsurprisingly that we see its semantic relation to the word 'auspicious', meaning 'sign of success'. Originally though, rather than the general meaning those have now, this was particular to divination, and is related to the word 'augur' which initially was an actual Roman officer whose job was as a diviner.
