Some people claim that they sometimes can use unusual words in a conversation but have forgotten the meaning of the word; sort of an unconscious remembrance of the definition of the word. Rather than thinking twice they just blurt it out. Later they look it up and it was exactly what they meant. They pride themselves on this ability, and I believe they should.

I'm not one of those people. Earlier today I was thinking to myself about something that since I've forgotten relating to photography. All of a sudden I said to myself, "That's a peridium!" I know now that I too remember words, but get the words and the meanings all mixed up. For a peridium, by definition, is "the covering of the spore-bearing organ in many fungi."
