Do you use unusual words? Do you like to read unusual words?

[PennyThompson]

I'm not sure I've ever used the word "onomatopoeia" in a sentence. It was hell in a spelling bee.

I can say it but I don't think I could spell it off the top of my head, thank god for spellcheckers

I think using unusual words in dialogue can be useful in establishing a character. It even allows for ambiguity about whether they are intellectual or merely pretentious.
There is, of course, the argument about when words are unusual. I have always read a lot, and occasionally, I have realised that people react unpredictably to using four-syllable words in ordinary conversation.
Going back to the use of ejaculated as a substitute for said, in some UK novels for children from the 1930s, brave young women are said to be full of spunk - in context, this clearly meant brave rather than the likely fate of a woman in a group sex story. I am still undecided if this was innocent back then or whether the authors were using the TV Trope of getting crap past the radar.
One upper-middle-class author of the 1930s included in one of her books the line, "He offered his cock to Lydia, who immediately flung a leg over it" I should add the cock was on a carousel. Personally, I think the double entendre was deliberate.

I am immensely grateful for their existence every time I try to spell “maneuver”. I’m pretty sure the vowels between n and v there rearrange themselves (and some get added or deleted, too) the moment you think you remembered them for good.

The answer to the question, @TheLobster, The word manure appears.

To add to your confusion, it's spelt manoeuvre in English English - and the original French.
