Can be confused
, transpire, vaporize
From its earlier literal sense “to escape as vapor” transpire
came to mean “to escape from concealment, become known” in the 18th century. Somewhat later, it developed the meaning “to occur, happen,” a sentence such as He was not aware of what had transpired yesterday
being taken to mean He was not aware of what had happened yesterday.
In spite of two centuries of use in all varieties of speech and writing, this now common meaning is still objected to by some on the grounds that it arose from a misapprehension of the word's true meaning.
