Sheer fluke意思

"Sheer fluke" is an English expression that means something happened by pure chance, without any planning or effort. The word "sheer" means absolute or total, and "fluke" in this context refers to an unexpected and unlikely occurrence, often with a hint of luck involved.

For example, if someone wins a lottery without buying a ticket, you might say it was a sheer fluke. It suggests that the outcome was entirely due to luck and not the result of any skill or strategy.
