Relating to or characteristic of epideictic rhetoric; meant for display or demonstration.
From Greek 'epi' + 'deiksis' (display, showing), with the suffix '-istic'. This is a less common variant of epideictic used occasionally in rhetorical studies.
This is another fancy word for the same concept—speech designed to show off and impress rather than to argue a point, which is why it appears in philosophical and rhetorical texts!
