While
“While” is a word in the English language that functions both as a noun and as a subordinating conjunction. Its meaning varies largely based on its intended function, position in the phrase and even the writer or speaker’s regional dialect. As a conjunction, it is synonymous with the word “whilst”, a form often considered archaic in American English, as well as in some style guides on both sides of the Atlantic.
