A diffused neologism is a word that a lot of people know and use, but hasn’t become common or mainstream or recognized as a word yet.
In this day and age of rapid technology development and social media, it doesn’t seem to take too long for new words to become mainstream. In fact, every year a new list of words and phrases is presented to the public as being deemed mainstream enough to be added to the dictionary.
I think that twins often use their own language that nobody else knows and understands, thus they would be using neologisms.
Often siblings or best friends have their own words that they understand but nobody else does.
I remember when my daughter was learning to talk, and she made up words for stuff all the time. She knew what the word meant, and I, as her mother, usually knew what the word meant, but it was tough on other people (like babysitters) who were trying to figure out what she was talking about. She clearly thought she was communicating exactly what she meant, but she was using her own little language for it, and nobody else knew what she was talking about. I bet lots of kids do this when they are first learning to talk.
And let’s face it….making up words is fun to do. What neologisms can you create this week?
