Delphic is an adjective that means obscure or ambiguous.

The Delphi in Greece was the site of a temple of Apollo. An oracle, or fortune teller, resided there. Her prophecies were often ambiguous and difficult to interpret. Today when we use the term Delphic to describe someone or something we’re not suggesting they have prophetic powers, but rather, that they are unclear or muddy.

Working with Tammy has been great, but I often wish she would be more direct and clear in her instructions. Last week’s orders were downright Delphic. We weren’t sure if she wanted us to deliver eight bottles of root beer or drink them.
