Head stones, also known as gravestones or tombstones, are markers used to identify and commemorate the deceased. While these terms are all commonly used to refer to the same thing, there are other synonyms that can also be used. One alternative term for head stones is epitaphs, which refers specifically to the words inscribed on the stone. Another possible synonym is cenotaphs, which are memorials erected in honor of someone who is buried elsewhere. In some cultures, the term stelae is used to refer to tall, upright stones used to mark graves. Regardless of the term used, head stones serve an important purpose in memorializing those who have passed away.
