* "For sake" is often used in a casual, informal way. It's usually part of a longer phrase like "for goodness sake," "for heaven's sake," or "for Pete's sake." These expressions aren't usually tracked formally like literary quotes.
* The word "sake" itself has a complex history. It comes from Old English "sacan," meaning "to strive" or "to argue." Over time, it evolved to mean "cause" or "purpose." So "for sake" could have originally meant "for the sake of," which is still used today.
* "For sake" might have multiple origins. It's possible that different phrases developed independently, with the common element being the idea of "for the sake of" something, whether it's goodness, heaven, or a person's name.
Here are some possible theories about the origins of specific "for sake" phrases:
* "For goodness sake": This might have originated from a time when people swore by the name of God, but softened it to "goodness" out of politeness.
* "For heaven's sake": This could be related to the idea of appealing to heaven for help or justice, or to show annoyance or frustration.
* "For Pete's sake": This might be a shortening of "for Peter's sake," where Peter is a common name and the phrase is meant to be a humorous way of expressing exasperation.
In conclusion, the exact origins of "for sake" are difficult to pinpoint. It likely evolved organically over time, influenced by changes in language and culture. Its meaning remains clear, however: it expresses strong emotion, whether it be exasperation, surprise, or simply a plea for understanding.
