It is an artificial infinitive noun (مَصْدَرٌ صِناعِيٌّ), an artificial infinitive noun.
Let's pick out the suffix يّ of حُرِّيّةٌ and think for a moment where else it appears. In Arabic, we call such words a Nisba (نِسْبةٌ or اِسْمٌ مَنْسُوبٌ).
You add يّ to any اِسْمٌ and get a word that can be used as an adjective (صِفةٌ), often to denote that someone is from a certain country or has a special profession. For example, Egyptian (مِصْرِيٌّ/مِصْرِيّةٌ).
Now, if we add a ة to a Nisba resulting in يَّة, it becomes a noun indicating an abstract meaning which it did not have before this augmentation.
We produced a so-called artificial infinitive noun (مصدر صناعي).
Many of such words describe abstract political, economic, or scientific terms (chemistry, biology).
