Other forms: neologizing; neologized; neologizes
To neologize is to invent a brand-new word, the way various writers did when they coined words like robot, blockbuster, and hangry.
The verb neologize comes from neologism, "new word or expression," which was neologized itself in the 18th century using the prefix neo-, "new," and the Greek logos, or "word." Writers and speakers neologize constantly, coming up with words to describe new ideas, cultural innovations, or technology. Many of these words are used briefly before fading away, while others catch on and become dictionary standards (think grok, gaslighting, or blog).
