Could someone please make a sentence with sepulcher.

It depends how you are using this word. Shakespeare used
it as a verb, but we seem to understand it as a noun.

It
directly mean to bury, according to Shakespeare. However, I could
easily see it used as burial, or burial
location.

Here's how I would use it each
way.

The serial killer had to
sepulcher each object with any DNA connecting him to the
murder in order to hide the evidence of his crime.

The
sepulcher was off the dirt road, down the hill and across a
dreary churchyard strewn with tombstones and decaying
flowers.

See if those work for you.
