It occurred to me that I was aware that there is such a word as 'amanuensis', but I had no idea what it meant, or how I became aware of the word's existence without also learning its meaning. So I looked it up on the internet and now do know what it means (I would share it with you, but I'd hate to think that this blog was educational in any way), but I still can't think where I heard it from in the first place.
I am friends with several pretentious people who like to use big words, it might have been from one of them, but perhaps I was asleep during the conversation and didn't pay attention to the context. Or maybe I came across it in some unnecessarily pompous factual book or article I read and didn't pay particular attention to.
Well, however I heard the word, I'm now enlightened and, being both pretentious and pompous, will do my best to use the word in everyday conversation and everyday bloggery as often as I can. And I'll maybe employ an amanuensis to transcribe my blog and show it to people who haven't got computers, so they'll all know how clever I am!
