A reader writes to ask:
I have always used two spaces after the end of each sentence and someone recently said they believed that was no longer the correct method to use. Can you tell me if I should leave one or two spaces between each sentence in a paragraph or is it one of those inconsequential issues?
I receive more email on this topic than any other. For such a simple question, it stirs up plenty of passion, controversy, and bile on forums where these sorts of things are discussed. I would like to advise you that it's an inconsequential issue, but clearly it is not for many writers and editors.
The roots of this debate go way back to the days of typesetting by hand, when two different styles of sentence spacing emerged. French spacing was the practice of setting a single space between sentences, while English spacing meant using two spaces. The two-space method carried over into the realm of the typewriter when that device was invented. If you learned typing on a typewriter, you were no doubt taught to put two spaces after every sentence, and two spaces after every colon, too.
