Expert writing Tips
Best practice
Prefer this construction over 'progressing slower' in formal reports or academic papers to ensure grammatical precision.
Common error
Avoid the double comparative error by saying 'more slower'. Since 'more' is already a comparative marker, it should be followed by the adverb 'slowly' rather than the comparative adjective 'slower'.

Ludwig's WRAP-UP
The phrase "progressing more slowly" is an essential tool in English for describing a reduced rate of advancement without implying a total stop. Ludwig AI confirms that this construction is the grammatically superior choice in formal writing compared to more colloquial alternatives. Its usage spans a wide variety of critical fields, from medical research—where it describes the rate of disease development—to economics and technology, where it tracks the pace of innovation or commercialization. By using the comparative "more slowly", writers maintain a professional and objective tone that is valued in academic journals like Nature and prestigious news outlets like The Economist. For those looking to avoid repetition, alternatives such as <a href="/s/advancing+at+a+slower+pace" target="_blank" rel="alternative">advancing at a slower pace provide the same meaning while shifting the structural emphasis. Ultimately, the phrase is a hallmark of clear, descriptive English used by experts to provide precise situational updates.
