means A marker, usually stone, placed over a grave to identify who's buried there with their name and dates.

from A straightforward compound of 'grave' (from Old English 'græf,' a place dug for burial, related to the verb 'to grave' meaning to dig or carve) and 'stone.' The word simply says what the thing does: a stone for a grave. Related terms like 'headstone' (marking the head of the grave) and 'tombstone' developed alongside it, with regional and period preferences for one word over another rather than any real difference in meaning.
