deverbate
Deverbate is a term used in linguistics to describe a word that has lost its verbal origin or function and now functions primarily as a noun or adjective. This process, known as deverbation, involves a semantic shift where the original action or state associated with the verb is nominalized or adjectivized. For example, the word "run" can function as a verb meaning to move quickly on foot, but it can also be used as a noun, as in "a long run," referring to the act or instance of running. Similarly, "happy" is an adjective, but its verbal root, likely related to "hap" or "happen," signifies a state of being.
The process of deverbation is common across many languages and is a natural part of language evolution.
