“Why is the symbol for ‘therefore’ (three dots in a triangle) rarely used in normal writing? Why does it not appear on a regular keyboard?”

(Answer requested by Roger Wilkey)

The “” glyph is used in mathematics and logic to symbolize “thus” or “therefore” in the same way that the ” = ” glyph is used to symbolize “equality” or “equals.”

But you’d never use ” = ” in a normal written sentence to replace the word “equality,” right?

Look how weird it is: “Dr. Martin Luther King worked for racial =.”

Using it in place of “equal” also is weird: “The Prime Minister is said to be ‘first among =s’.”

, er, I mean, therefore (see how weird it looks?) you’d also never use (or most of the other specialized symbols from a myriad of professions) in standard written English typed on standard keyboards, either.

    1. (alt+8756) works in Word, but not anywhere else that I’ve tried. If you’re using Windows, try Character Map and look in the Symbols font.

      1. On an iPhone, Google glyphboard in Safari, save it as a Home page shortcut, and then use the shortcut to copy a symbol to your clipboard. I’m sure one of my iOS clipboard apps could be useful, too.
