Did You Know?
"Transpire" came to life in the late 16th century and was originally used in technical contexts to describe the passage of vapor through the pores of a membrane. From this technical use developed a figurative sense: "to escape from secrecy," or "to become known." That sense was often used in ambiguous contexts and could be taken to mean "happen." (For example, Emily Dickinson wrote in a letter, "I long to see you once more ... to tell you of many things which have transpired since we parted.") Thus the "to take place" sense developed. Around 1870, usage critics began to attack this sense as a misuse, and modern critics occasionally echo that sentiment. But the sense has been common for two centuries and today is found in serious and polished prose.
