Final answer:
The hand sign of Alpha Xi Delta is typically internal to the sorority's culture and may not be public knowledge or documented in academic or scholarly resources.
Step-by-step explanation:
The hand sign of Alpha Xi Delta, a National Panhellenic Conference sorority, is not officially documented through academic materials or widely recognized references. Sorority and fraternity signs are often a part of internal culture and ritual, and as such, they may not be openly shared with the public or appropriately documented in scholarly sources. It's essential to respect the privacy and rituals of Greek letter organizations, which can include confidential hand signs and gestures.
When considering gestures and their meanings, historical context like that provided by Quintilian in Institutes of Oratory highlights the intricate relationship between body language and communication throughout history. Similarly, the concept of hand signs can be linked to symbols and meanings, such as the Greek Alphabet or the right-hand rule in mathematics and science, which illustrates the directional relationship between three-dimensional axes.
