Interesting Words - Elementary

Sad to say, Sherlock Holmes never said ‘Elementary, my dear Watson!’ in the books written by Sir Arthur Conan Doyle.

(Holmes did use the word ‘elementary’ in The Crooked Man (1894):-

“I have the advantage of knowing your habits, my dear Watson,” said he.
…
“Excellent!” I cried.
“Elementary,” said he.

The phrase, ‘Elementary, my dear Watson’ was penned 21 years later by P.G. Wodehouse in his novel Psmith, Journalist, and the phrase is also uttered at the very end of the 1929 film, The Return of Sherlock Holmes, the first Sherlock Holmes sound film.)
