Since Max began this thread I have been unable to stop myself from creating words for any and everything that comes my way. Some of the words I have come up with - braichy, kielterate, wraid, and droozy. I love them. They are nonsense with a veneer of seriousness.
I learned while looking for a word if you concentrate on the word you have inordinate difficulty, where as if you concentrate on what you are trying to describe the word will come to you - and often it is a word that surprises you with its uniqueness.
I had wanted a word for rainy sky that flickered continuously like a tube light and roared like a train engine. I have come up with rumblickering or with onomatopoeic effect "a brumblickering sky". Makes sense? Of course not...
But the idea is to see what words one can come up with and not to use the words to communicate - that won't work …
