come hell or high water
Meaning
No matter what happens; despite any difficulties, obstacles, or danger, something will definitely be done or will happen.
Origin
Recorded from the late 19th–early 20th century. “High water” refers to flooding or dangerously high tides; paired with “hell” to intensify the idea of extreme obstacles.
Notes
Emphatic and resolute; implies determination despite serious obstacles. Works in speech and writing, but can sound dramatic or forceful, so use when commitment is strong.
