Make Your Editor Cry: Case And Point vs. Case In Point
If you’ve just finished a flawless argument, the last thing you want to do to cap off your brilliance is trip up an idiom with an eggcorn.
The intended meaning of the idiom is to direct attention to the fact that the present entire case (situation or argument) lends credence to, and supports, your main point. That is, that it demonstrate how the entire case lies in the final specific point.
The intent is not to have both a case and a—potentially separate and unrelated—point.
The correct expression is case in point.
Example:
This week's game is a case in point.
Gregg Bridgeman is the Editor-in-Chief at Olivia Kimbrell Press. He is husband to best-selling Christian author Hallee Bridgeman and parent to three. He continues to proudly serve in the US Armed Forces and has done so in either an active or reserve capacity for more than twenty years as an airborne and air assault qualified paratrooper, earning a Bronze Star for his service. Most importantly, he was ordained in October of 2001 after surrendering his life to Christ decades earlier.
