What is the superlative and comparative degree of modern?

The word "modern" is already in the positive degree. It doesn't have a comparative or superlative form in the traditional sense.

Here's why:

* Modern is a relative term that describes something belonging to or characteristic of the present or recent times. There isn't really a "more modern" or "most modern" because something is either modern or not.

* To express a higher degree of modernity, we often use other words or phrases:

* More contemporary

* More up-to-date

* The most recent

* The latest

For example, instead of saying "This is the most modern building," you might say "This is the most recent building" or "This is the most contemporary building."
