Grammar Hammer: Sherlock Holmes and the Mystery of the Semicolon
If a comma represents a brief pause, and a period represents a complete stop, then semicolons represent a moderate pause.
Semicolons are used in two main environments:
Semicolons can act as “super commas,” which are used to separate units of a list when one or more of the units contain commas:
- Holmes found three clues: footprints, which were outside the door; a pistol, which was still loaded; and papers, which smelled of cyanide.
- The murderer visited three cities: Liverpool, England; Paisley, Scotland; and Lusaka, Zambia.
Semicolons can also be used to connect clauses:
Use a semicolon in place of a period to connect or form a bond between two statements (typically related or contrasting thoughts) where the conjunction has been left out:
- Professor Moriarty is a criminal mastermind; he is the “Napoleon of Crime.”
- Watson received his medical degree in 1878; he is a surgeon.\
Use a semicolon before transitional phrases or conjunctive adverbs that connect two clauses (like however, therefore, that is, namely, of course, for example, thus):
- The copper-haired girl was hired as a governess; however, she was unknowingly posing as her employer’s daughter.
- One sister died with a shout of “It was the speckled band”; of course, Holmes knew she was referring to a swamp adder.
But don’t use semicolons before simple conjunctions (words like but, and, or, nor, for, so, yet):
- Watson led from behind, but never gets the credit he deserves.
- Holmes had a brother named Mycroft and he was more brilliant than Holmes himself.
Optional: You may use a semicolon between two clauses when one has internal punctuation, or in other words, if a one or more commas appear in the first or second clause:
- If Holmes can, he will give up cocaine; and if Watson can see it through, they will solve mysteries again.
- When Arthur Conan Doyle started writing Sherlock Holmes short stories, he created the field of criminology; however, at the time, he never thought he was changing the world.
