Ludwig's WRAP-UP

The phrase "in certain instance" is grammatically incorrect; the correct form is "in certain instances". As highlighted by Ludwig AI, the proper usage involves the plural form of "instance" to denote multiple or unspecified occurrences. This phrase functions as an adverbial modifier, specifying conditions under which an action or event takes place. While its intended meaning is clear—to indicate that something applies only under specific conditions—the grammatical error undermines its effectiveness. For more accurate and polished writing, consider alternatives such as "in certain cases" or "in certain situations".
