Stenching is defined as having an offensive, unpleasant odor. Synonyms for stenching include putrid, pungent, foul, malodorous, noxious, rancid, repugnant, reeking, smelly, rank, stale, and acrid. Each of these words describes a similar, unpleasant smell that can be overwhelming and uncomfortable for those who are exposed to it. Stenching odors can come from a variety of sources, including decomposing organic matter, chemicals, and bodily fluids. When dealing with stenching odors, it is important to take appropriate measures to eliminate the source and improve air quality, such as ventilating the area and using air fresheners or odor eliminators.
