Expert writing Tips
Best practice
When describing duration or length, use "longer" instead of "more longer" to ensure grammatical correctness. For example, say "the meeting lasted longer than expected" instead of "the meeting lasted more longer than expected".
Common error
Avoid using both "more" and the comparative form "-er" (as in "longer") together. This creates a redundant comparison. Choose either "more long" (though "longer" is preferable) or simply "longer".

Ludwig's WRAP-UP
The phrase "more longer" is a grammatically incorrect construction that should be avoided. As Ludwig AI confirms, the correct form is simply "longer". Although the phrase appears with some frequency across various sources like News & Media and Science, its use detracts from clarity and professionalism. When aiming to express a greater duration or extent, it is best to use the concise and correct adjective "longer". Using phrases like "for a longer time" or "of greater duration" can add formality and precision when needed, but "longer" remains the most straightforward and grammatically sound option.
