What is what the comparative and superlative degree of holy?

The word "holy" is an adjective that already describes the highest degree of something being sacred or pure. There is no comparative or superlative form of "holy."

Think of it this way: Something can be holy or not holy, there are no degrees of holiness.

However, if you want to express a difference in degrees of sacredness or reverence, you could use phrases like:

* More sacred/reverent

* Most sacred/reverent

* Highly sacred/reverent

* Deeply sacred/reverent

For example, you could say:

* "The cathedral is a more sacred place than the chapel."

* "The temple is considered the most sacred site in the religion."
