The Merriam-Webster dictionary has a feature that allows you to look up by year the time words were first published. One curious thing I noticed is that there are huge numbers of words introduced in the 40s on, most of them technical and scientific words, but in more recent years the number of novel words is drying up. Why? I don’t know.
I did look up what words were introduced in the year I was born, and there were lots of them. But this series caught my attention.
I think it means that emotionally I am far more childish than my advanced years would imply.
