Ludwig's WRAP-UP
In summary, while the phrase "per subjects" appears in some scientific literature, it is generally considered grammatically incorrect. Ludwig AI suggests that the proper construction is "per subject" (singular) or using alternative phrases like "for each subject" or "for every subject". The phrase attempts to express a rate or ratio on an individual basis, but its incorrect grammar detracts from its clarity and appropriateness, especially in formal writing. It's better to adopt alternative phrasings to ensure grammatical correctness and prevent potential misinterpretations.
