Detailed Explanation
What Does “Case in Point” Mean?
A case in point is an example that clearly demonstrates a particular argument or rule. The phrase is used to point to a specific instance that supports the speaker’s claim. For instance:
“The new policy’s failure to reduce traffic congestion is a case in point of how poorly planned regulations can backfire.”
Here, the policy’s failure is the example that proves the broader argument about planning.
Origin of the Phrase
The expression dates back to the late 19th century, appearing in legal and literary contexts. Plus, it combines the noun case (a specific instance or example) with in point, meaning directly relevant or precisely illustrative. The phrase was popularized by writers such as George Eliot and James Whitcomb Riley, who used it to underscore a point in their narratives.
Why “Case and Point” Is Incorrect

Even so, the word point in the idiom is not a noun that can be joined by “and.” It functions as part of the prepositional phrase in point. So, inserting and breaks the grammatical structure and creates a nonsensical phrase. Even native speakers sometimes slip into this error, especially in informal speech Small thing, real impact..
