The opposite of "more reeking" might be "less odorous." The word "reaking" connotes a strong, foul odor, so an antonym would refer to an absence or reduction of that odor. Other potential antonyms might include "fragrant," "clean," "fresh," or "pleasant-smelling." As an adjective, "more reeking" suggests a smelly, unpleasant environment or object, while the antonyms suggest a more pleasant or neutral atmosphere. In some cases, the antonym might refer to a completely different sense or experience altogether, such as "tasty," "colorful," or "quiet." Ultimately, the choice of antonym will depend on the context and the intended meaning of the original phrase.
