Final answer:
Isolated graves are solitary burials that are set apart from others, possibly due to unique circumstances or the individual's status, whereas adjacent graves are located next to each other within a communal burial area, reflecting societal connections or family bonds.
Step-by-step explanation:
When discussing isolated vs. adjacent graves, the terms refer to the location and proximity of burial sites to one another. Isolated graves are those that are located apart from other graves, typically because of unusual circumstances such as distance from the main burial area, social status, or specific historical events. These graves might be the resting places of individuals who were ostracized, important figures requiring separate commemoration, or casualties of conflict buried where they fell. Conversely, adjacent graves are burial sites that are situated next to each other, usually within a defined cemetery or burial ground. They are often part of a planned layout, reflecting societal relationships or family ties, where individuals are buried in proximity to others as part of a collective group or a familial plot.
