[French transpirer, from Medieval Latin trānspīrāre : Latin trāns-, trans- + Latin spīrāre, to breathe.]
Usage Note: Transpire has been used since the mid-1700s in the sense "to become publicly known," as in Despite efforts to hush the matter up, it soon transpired that the colonels had met with the rebel leaders. While this usage has been considered standard for generations, it appears to be on shaky ground and could be headed for obsolescence. In our 2001 survey, 48 percent of the Usage Panel rejected it in the sentence quoted above. It might be better to use a synonym such as become known, leak out, or get around. · The more common use of transpire meaning "to happen or occur" has a more troubled history. Though it dates at least to the beginning of the 1800s, language critics have condemned it for more than one hundred years as both pretentious and unconnected to the word's original meaning, "to give off as vapor." But there is considerable evidence that resistance to this sense of transpire is weakening. In our 1966 survey, only 38 percent of the Usage Panel found it acceptable; in 1988, 58 percent accepted it in the sentence All of these events transpired after last week's announcement. In 2001, 66 percent accepted the same sentence. Nonetheless, many of the Panelists who accepted the usage also remarked that it was pretentious or pompous. This usage is easily avoided by saying happen, occur, or take place instead.

The next place the guide took us to in the holy church was an altar dedicated to the Roman soldier who was of the military guard that attended at the Crucifixion to keep order, and who--when the vail of the Temple was rent in the awful darkness that followed; when the rock of Golgotha was split asunder by an earthquake; when the artillery of heaven thundered, and in the baleful glare of the lightnings the shrouded dead flitted about the streets of Jerusalem--shook with fear and said, "Surely this was the Son of God!" Where this altar stands now, that Roman soldier stood then, in full view of the crucified Saviour--in full sight and hearing of all the marvels that were transpiring far and wide about the circumference of the Hill of Calvary.
