Here is a funny word that I learned while reading The Complete Casebook of Herlock Sholmes. Usually the context is satire against government. So imagine my surprise when I found this word in The Valley of Fear, one of The Greatest Adventures of Sherlock Holmes. There is no satire in this context, just the plain meaning of the word.
“It may have been that his attentions to Ettie had been more evident than before, or that they had gradually obtruded themselves into the slow mind of his good German host; but, whatever the cause, the boarding-house keeper beckoned the young man into his private room and started on the subject without any circumlocution.”
